ImT0t4llyL4m3 I’m just giving feedback. I’m sorry if I offended anyone. It’s just that I think more people should fix their English, or at least learn the very basics first. I understand that this might be offensive, but it’s kind of irritating seeing people who can’t even use a full stop properly. (Also, on second thought, minni cute, you english is actually pretty good)
@@MCConfuz This trick relies on the assumption that every square you are being given is the square of an integer. Someone might feed you numbers that are the squares of non-integers. Suppose in his original example instead of 1156 it was 1151 if you applied his tricks you would think the answer was either 31 or 39 when in fact its actually 33.92939...
You can also add the digits of the numbers until you get one digit like if you add the digits of 13 you get 4. If you take the square of 13, it has to add to the same amount as 4x4. 4x4 is 16. 1+6 is 7. So the digits of the square of 13 also have to add to 7. The square of 13 is 169. Add the digits: 1+6+9=16, 1+6=7. So if you can’t tell by looking which is closer, add the digits of the numbers until you get one digit. Take the square and add the digits until you get one number. Look at your two choices and add their digits until you get one number and see which one matches. Let’s say you’re deciding between 43 and 47. The number that is the square of one of these numbers is 2209. 2+2+0+9=13, 1+3=4. What’s the square root of 4? 2. So when you add the digits of the square root of 2209, it has to add to 2: 4+3=7 so it can’t be 43. 4+7=11, 1+1=2. It’s definitely 47. The only time this doesn’t work is when you are choosing between multiples of 3. For example, 42 and 48. The digits of both their squares will add to 9. So you have to guess. These one digit numbers that all numbers add down to are called digital roots. You can add the digits as I did or you can enter a number on a scientific calculator and hit mod 9 to get the digital root. These digits are also the remainders when you divide by 9. Adding them and multiplying them is part of modular arithmetic.
This guy is helping so much to cover 3 year of classes I had no idea how to solve I only knew perfect squares and now I understand finally after hours of searching the perfect video for me to understand
Thanks a lot Sir Tomorrow is my exam and I didn't know how to break square root but I will find any root number after watching this video Love from Aligarh, INDIA 🇮🇳
Lovely teaching! Also instead of doing: For example on the square root of 2304: its either 42 or 48 and instead of finding the square root of 40 and 50, you can find the square root of 45 which is in the middle of both numbers. An easy way to work out how to square numbers ending in 5: 5 x 5 is *25,* then keep that. for 45, you have done the 5 and you have 4 left. Add one to that number then times both numbers: 4 times 5 which gives you *20.* Put the numbers together in the order they were in: 4 5 20 25 Your answer is 2025 The original number was 2304 (The number that you had to work out the square root of) which is higher than 2025 so the answer has to be higher too. The answer is 48. Sorry If I didnt explain well, I just think this is a helpful way to do it. It is a bit faster. :)
This guy is AMAZING! I was absent last friday because i was ill and missed a lesson. When i got back to school i asked my Teacher what i missed so he asked my classmate to explain, I didnt quite understand because he kept laughing the whole explenation so i just pretended i got it. After class i searched this guy and finally got it. Hes better than my Teacher.❤❤
Glad! SO GLAD The Organic person exist! Not only his voice give a sense of peace and easy mind focusing, he is explain awesomely. Thanks for you! Mr. The Organic
omg i rlly was struggling thank u rlly so much u rlly deserve the money i pay for the whole school idk why teachers dont teach us this im an 11th grader and i just knew it 😭😭😭😭😭
Hey man, I'm speaking as young as 13! Amazing strat, I honestly would ever be amazed to have you as my math teacher but I appreciate the fact that I took this lesson online. I look forward to more of your videos, please keep it up! :D
There was a mistake in the 15^2 it is actually 225 for people who are confused or thought they remembered wrong but very good method overall!thanks for sharing
How did you get square root 9 and 16 from square root 11? This part confused me a lot. For anyone who is confused, Square root 11 is between perfect square root of 9 and 16 . If it was square root of 30, it would be between perfect squares of 25 and 36. All perfect squares are: 1 4 9 16 25 36 49 64 81 etc...
An easier way to find the unit digit is to multiply the 10s digit by its next consecutive number. That is 3*4=12. Since 12 is larger than 11 you take the smaller digit 3. If 11 was larger than this product you would take the larger 6.
I learned so much with this dude, throughout 7th and 8th grade, now I'm in 9th and we are about to discuss factorials, something i learned from this dude when i was in 7th grade. 😅
I love this, so useful. I fell like I was somewhat failed by my mathematics education, realsing in my adult life that other people had been taught long division on paper and Venn diagrams and square roots that I had no idea about. I just thought I was bad at it. But just Googling how to mentally work out square roots, so that I could have rough ideas of perimeters of given areas without having to defer to a calculator I found this. I found it so simple and got it instantly and it reminded me that i am not so bad at numbers. Thank you!
Let's use your last example - 24649 Now last digit or we say the digit at unit place is 9 so unit digit of sqrt. Of the given no. Should be either 3 or 7, now the nearest square of a no. is 225 which is equal or smaller than 246, so we take the sqrt of 225, i.e 15 now the desired answer could be either 153 or 157 for that we have to just multiply 15 by 16 i.e 240 (now we will check if 240 is smaller or equal to 246) 240
You are amazing! I have viewed many of your videos on chemistry, physics, and mathematics. All my problems are resolved once I go through your videos. The way you explain how to solve a problem is far superior to any other STEM videos that are seen on TH-cam.
This totally works for any digit number, you just need to expand the lines. Each starts one more digit to the right. The first line is digits right next to each other, the next is numbers one apart, the next 2 apart and so on until the last line is the first digit times the last digit. With a little practice, I was squaring a 6 digit number in under a minute.
One more trick, that really should be here... Taking the example of the square root of 4489, rather than asking if this is closer to 60^2 or 70^2, we consider 65^2 = 60*70 + 25
Sir🙏My heart felt gratitude to you. I am the average student who thinks maths is difficult that too very weak in Maths. You have made Maths so understandable and I'm loving maths. Salute to you..you made my day sir..🙇♀️ My 10th board's are near and I will surely remember you and your tricks in exam hall.
There is also another method mentioned by Presh Talwalkar While finding a root of a number by this method, you may get 2 numbers to decide on. You can take the sqaure of the middle number which would be tge 5th term For example: For root of 24649 You have 2 options: 153 or 157 Now you can take the sqaure of the middle term which would be 155. There is a brilliant trick to find the square of a number ending in 5 Suppose 45 sqaured. Now leave the last digit which would be 5, so you have 4. Now multiply 4 with the number after itself, so: 4*5 which is 20. Now add 25 as the last 2 digits of the number so 45 squared is 2025
There’s another way to do it, too. After determining the two possible digits in the ones column, ignore the last two digits, and find the nearest square below the remaining numbers and find the root. That’s the number for the tens column. Multiply that number by the next number up. If the product is smaller than the number left of the ignored digits, pick the larger number for the ones column.
MR. Organic Chemistry Tutor, thank you for another monster video/lecture on How to find the square root of large numbers mentally. This topic shows some mathematical tricks that all students should know in Mathematics. There are different methods for computing the square root of large numbers.
Hey dude, they did not teach it, because the trick is totally useless for calculating anything in any real maths situation you will ever encounter in your life. If you didnt quickly notice this fact, you are not doing, (or going to do) very well in maths related subjects.
@@jovem3767 they would just give you a calculator but would be useful if u can solve it quicker than typing it into a calculator or if u want to impress ur teacher

This guy is saving my life. I don't need to spend 10 countless minutes figuring out square roots anymore. Give this man a gold medal
I know right! Keep up the great work!👍
The big problem with your method is that it only works if you are sure that the given root has an integer solution. If you don't know this, you should use the approximation formula Sqrt(n² + a) ≈ n + a/(2n) and (n + 0.5)² = n * (n+1) + 0.25 for better squares between the squares of natural numbers.
*RULESET*
Given: Sqrt(x)
*(1) Remove redundant powers of 10*
If x > 1000: 10 * Sqrt(x/100)
If x > 100,000: 100 * Sqrt(x/10,000)
If x > 10 * 10^(2k): 10^k * Sqrt(x/10^(2k))
New Radikand: y = x/10^(2k)
Advantage: 10 < y < 1000
You only need Square numbers of 1 to 31.
*(2) Find the closest square number n*
Bonus: If the number is relatively centered between two square numbers n1 and n2, you can form the product of these and add 0.25 (n1 * n2 + 0.25) to use the square number (n1 + 0.5)².
*(3) Calculate the difference*
a = y - n²
*(4) Use approximation formula*
Sqrt(y) = Sqrt(n² + a) ≈ n + a/(2n)
-------------------------------------
Examples:
Sqrt(1156) = Sqrt(11.56 * 100) = 10 * Sqrt(11.56) = 10 * Sqrt(12.25 - 0.69) = 10 * Sqrt(3.5² - 0.69) ≈ 10 * (3.5 - 0.69/(2*3.5)) ≈ 10 * 3.4 = 34
Sqrt(2304) = Sqrt(23.04 * 100) = 10 * Sqrt(23.04) = 10 * Sqrt(25 - 1.96) = 10 * Sqrt(5² - 1.96) ≈ 10 * (5 - 1.96/(2*5)) = 10 * 4.8 = 48
Sqrt(4489) = Sqrt(44.89 * 100) = 10 * Sqrt(44.89) = 10 * Sqrt(42.25 + 2.64) = 10 * Sqrt(6.5² + 2.64) ≈ 10 * (6.5 + 2.64/(2*6.5)) ≈ 10 * 6.7 = 67
Sqrt(12996) = Sqrt(129.96 * 100) = 10 * Sqrt(129.96) = 10 * Sqrt(132.25 - 2.29) = 10 * Sqrt(11.5² - 2.29) ≈ 10 * (11.5 - 2.29/(2*11.5)) ≈ 10 * 11.4 = 114
Sqrt(24649) = Sqrt(246.49 * 100) = 10 * Sqrt(246.49) = 10 * Sqrt(240.25 + 6.24) = 10 * Sqrt(15.5² + 6.24) ≈ 10 * (15.5 + 6.24/(2*15.5)) ≈ 10 * 15.7 = 157
And for error estimation for the approximation formula you can use the following term:
Error = a²/(8n³)
With a < n:
Error < n²/(8n³) = 1/(8n)
-------------------------------------
Without the 0.5 formula:
Sqrt(1156) = Sqrt(11.56 * 100) = 10 * Sqrt(11.56) = 10 * Sqrt(9 + 2.56) = 10 * (3² + 2.56) ≈ 10 * (3 + 2.56/(2*3)) ≈ 10 * 3.4 = 34
Sqrt(4489) = Sqrt(44.89 * 100) = 10 * Sqrt(44.89) = 10 * Sqrt(49 - 4.11) = 10 * Sqrt(7² - 4.11) ≈ 10 * (7 - 4.11/(2*7)) ≈ 10 * 6.7 = 67
Sqrt(12996) = Sqrt(129.96 * 100) = 10 * Sqrt(129.96) = 10 * Sqrt(121 + 8.96) = 10 * Sqrt(11² + 8.96) ≈ 10 * (11 + 8.96/(2*11)) ≈ 10 * 11.4 = 114
Sqrt(24649) = Sqrt(246.49 * 100) = 10 * Sqrt(246.49) = 10 * Sqrt(256 - 9.51) = 10 * Sqrt(16² - 9.51) ≈ 10 * (16 - 9.51/(2*16)) ≈ 10 * 15.7 = 157
as long as you only ever run into perfect squares you'll be golden

Lovely teaching! Also instead of doing: For example on the square root of 2304:
its either 42 or 48 and instead of finding the square root of 40 and 50, you can find the square root of 45 which is in the middle of both numbers.
An easy way to work out how to square numbers ending in 5:
5 x 5 is *25,* then keep that.
for 45, you have done the 5 and you have 4 left.
Add one to that number then times both numbers: 4 times 5 which gives you *20.*
Put the numbers together in the order they were in:
4 5
20 25
Your answer is 2025
The original number was 2304 (The number that you had to work out the square root of) which is higher than 2025 so the answer has to be higher too. The answer is 48.
Sorry If I didnt explain well, I just think this is a helpful way to do it. It is a bit faster. :)

How did you get square root 9 and 16 from square root 11? This part confused me a lot.
For anyone who is confused, Square root 11 is between perfect square root of 9 and 16 . If it was square root of 30, it would be between perfect squares of 25 and 36.
All perfect squares are:
1
4
9
16
25
36
49
64
81
etc...
An easier way to find the unit digit is to multiply the 10s digit by its next consecutive number. That is 3*4=12. Since 12 is larger than 11 you take the smaller digit 3. If 11 was larger than this product you would take the larger 6.

Now last digit or we say the digit at unit place is 9 so unit digit of sqrt. Of the given no.

A useful trick is that a square of #5 number is # x (# + 1) +25, eg 65 squared is 4225 so you quickly see if you go up or down.
u mean n*(n + 1) then + 25 in the end? Like 6*(6 + 1) is 42 then add 25 in the end, so we got 4225?

Suppose 45 sqaured. Now leave the last digit which would be 5, so you have 4. Now multiply 4 with the number after itself, so: 4*5 which is 20. Now add 25 as the last 2 digits of the number so 45 squared is 2025
Thank you so much sir, I am very glad to have you . I'm from India sir , Thank you so much
There’s another way to do it, too. After determining the two possible digits in the ones column, ignore the last two digits, and find the nearest square below the remaining numbers and find the root. That’s the number for the tens column.
Multiply that number by the next number up. If the product is smaller than the number left of the ignored digits, pick the larger number for the ones column.
Wish you could write out an example with numbers (like a teacher). Words get me all confused.
@@EmpyreanLightASMR this is where that trick comes from, the guy in the video explains it with examples th-cam.com/video/nUyLnjgGumg/w-d-xo.html
@@EmpyreanLightASMR yeah
It doesn’t always work I tried
Try to find the square root of 959
you are so smart 👍👍👍
I don't believe there is another person like you 👍
You're the best sir, in everything
Tysm man! This helps 🎉
Lots of love from india, dear sir it helps me alot.
❤❤❤❤❤❤❤❤
im in pre-algebra and this helps me out a lot
WHAT ABOUT IF THE NUMBER ENDS WITH A 2
Fraction or decimal rounded off, or just leave be since it is not a perfect square
I wish i've known this during my school days. Thanks a lot. i'll show this to my kids.
Thank you
Probably the best teacher on TH-cam. Only this channel can explain us
this is the voice that soothes me, this
this is it
MR. Organic Chemistry Tutor, thank you for another monster video/lecture on How to find the square root of large numbers mentally. This topic shows some mathematical tricks that all students should know in Mathematics. There are different methods for computing the square root of large numbers.
Many thanks 😊
May God richly bless you ❤😊
Thank you sir ,it is very easy now to calculate any large value of square root ....
No it isnt. You can only find the sqrt of a perfect square, which are rare
Very nice video !!! Love it , just awesome and so useful
OMG! Where were you during my schooling ?
THANK U THANK U THANK U THANK U
after learning this,
Me: A father of mathematics has born😂
😂😂
😄
susey baka
Super method
The people who disliked this [no words] video are the teachers who failed teaching this to their students.
Hey dude, they did not teach it, because the trick is totally useless for calculating anything in any real maths situation you will ever encounter in your life.
If you didnt quickly notice this fact, you are not doing, (or going to do) very well in maths related subjects.
@@ronalddump4061 all that matters is it helped, whether you learned it differently or not, it doesn't matter.
I'm from india , i like your teaching style sir. Thanks
This is mind-blowing 😮😮😮😮😮...
U are the best ❤
TH-cam Guy better math teacher than math teacher, no big surprise.
2:26, if you look at 15 squared, it says 215 when it should be 225, just here to point that out but thank you so much for your wonderful videos.
We need something explaining when numbers are not perfect squares and when the square number ends in 8 🙏
thank you for helping my 12 year old, as she is learning this!
Very helpful and correct this is a god send wish you the best
good video
For this video your channel will never rotates back
Bro, u deserve a platinum medal...
Thank u so much. Makes mathematics so much easier
Mr. Organic Chemistry, I love your lessons. Thank you soooooooo much.
Now this is really neat!
Will I ever need this? No. But do I know how to do it just in case? Yes. Thanks.
I think you will, if you are at school
@@jovem3767 they would just give you a calculator but would be useful if u can solve it quicker than typing it into a calculator or if u want to impress ur teacher
@@Zem1e yea real
In case of what?
There is no case in the real math world where this trick could help you with anything
You are so amazing! 👍👍👍
Wow! Fantastic as always. Has to be a perfect square though, right?
I am 8th grade I love maths thanks for this video👌👍
Thanks for your time to help me and everyone around the world ❤❤❤❤
Thank you for such valuable info
I have just experienced the biggest maths déjàvu in my life.Picture this: I am practicing solving square roots by long division and after I solved the first example in that way, The second problem is the one exact number (namely 2304) that I have just solved on another maths channel right before watching this video.LOL😂
Very nice class
Its just like we are learning multiplication tables😂😂❤❤❤
Realllllyyyy helpful, I have no words left for you , suck a good teacher
