Thanks for posting these. My son is in year 7 now (2024) and they teach them so little in school then expect them to pass exams. We are having to do all the work at home so your videos are gold.
Thank you for the kind words! I'm sorry your son's school isn't covering everything, but I'm glad I've been able to help and please feel free to reach out if you have any questions 👍
Good question! You only add exponents when you're multiplying 2 terms and the bases are the same. Here, the bases were never the same: we had a 2 and 3. So that's why we would never add the exponents in this case 👍
Is there a video about adding different exponents? That'd be nice because I am quite stuck with it, and my dad is expecting me to solve it. Please do help
Hi sorry just saw your comment! There's no rule on adding exponents, you simply have to evaluate each term individually first, and then add them together at the end - hope that helps!

Another way we can solve exponents is by splitting them up. Here an example: th-cam.com/users/shortsbDhJuZUwYUw?si=jXgKY1wV_ut-2VIw For your specific problem, we can split it up like this: 6⁴ x 8³ 6 x 6³ x 8³ 6 x (6x8)³ 6 x (48)³ This is about as simplified as we can write it, but you could plug it into your calculator to get a final answer: 6 x 110,592 = 663,552 👍
First thing you notice is the negative exponent. Negative exponent flips the number into a fraction. So: 8x-² = 1/8x² When you flip it into a fraction, make sure to turn the exponent POSITIVE. So the real problem is 1/8x² * 9x² To multiply Fractions, just multiply straight across. So on top we have: 1*9x² = 9x² On the bottom we just have 8x² So the complete fraction is: 9x²/8x² Notice we have an x² on the top and bottom, so they cancel out. So all we're left with is 9/8 That's the final answer 👍 Hope that helps!
If you're going to calculate 54^2, you might as well just calculate, without reducing, 2^2 x 9^3 to begin with. I mean, this technique really doesn't simplify the math, if one wants a final number.
LOL No worries! All I'm doing is rearranging the exponents a bit to simplify the problem. When solving exponent problems, you want to match up either the bases or exponents. In this example, the bases are 2 and 9. They dont divide evenly into one another so we cant match them up. So instead, i tried matching up the exponents. 2² is already very simplified so I cant really break it down in any way and rewrite it. However. We can re-write 9³, specifically as (3²)³, because that way we can match up the '2's as an exponent on both numbers. I hope that helps but please let me know if you still have questions! 👍

My bro knew the square of 54 in a sec 🗿
bro is a friggin genius
yes why not he's really a genius
That's not so hard I can do it 🗿🗿
Thanks man, U really made me not fail my exam, getting a 6/7 instead of last years 4/7
Great job, that's awesome! And I'm happy I could help :D
bro god bless you i watch ur vid before every test xD
lmao I'm happy to help! And I think I might start doing some test review videos in that case 😄
you have a new subscriber because of this thanks
That means a lot, thank you for the support, I'm really glad I could help! 🙏
Thanks dudeeee i have a test today and this gonna help ❤️❤️❤️
GL on your test, youre gonna crush it u friggin genius! :D
Why didnt the two squares not get added??

@@Eat_Pi Ah, I see. Thank you for your information
Haha thanks i have a entrance exam to go back to my old school that i left thanks
Goodluck on your exam! Ur gonna crush it 💪😎
How to multiply different bases but same exponent?
Here is a video on how to do that:

What would 6'4 x 8'3 be? I got 96'3 but I think it's wrong
Another way we can solve exponents is by splitting them up. Here an example: th-cam.com/users/shortsbDhJuZUwYUw?si=jXgKY1wV_ut-2VIw
For your specific problem, we can split it up like this:
6⁴ x 8³
6 x 6³ x 8³
6 x (6x8)³
6 x (48)³
This is about as simplified as we can write it, but you could plug it into your calculator to get a final answer:
6 x 110,592
= 663,552 👍
Are you from which country
Hello, guys I have a trick the question is 2² × 9³
Solution :- 2² = (2×2)×(9×9×9)= 2916 simple.🎉
(8x-²) (9x²)
First thing you notice is the negative exponent. Negative exponent flips the number into a fraction. So:
8x-² = 1/8x²
When you flip it into a fraction, make sure to turn the exponent POSITIVE.
So the real problem is 1/8x² * 9x²
To multiply Fractions, just multiply straight across. So on top we have:
1*9x² = 9x²
On the bottom we just have 8x²
So the complete fraction is:
9x²/8x²
Notice we have an x² on the top and bottom, so they cancel out. So all we're left with is 9/8
That's the final answer 👍
Hope that helps!
im a genius nobody has ever said that to me
Get ready to join MENSA buddy
@Eat_Pi ok
Thanks i have my exams tomorrow
Hope you crushed that exam like a friggin genius 💪

Thank a lot you clear my dout
You are most welcome!
What if the power of the other exponent is will not be the same even after flipping?
That's a good question, do you have a specific example in mind?
@@Eat_Pi 16 to the power x+1 +20(4 to the power 2x)
helps alot
That's awesome to hear! :D
Thank u so much
Bro how do you got 27
Great question!
3³ = 3 x 3 x 3 = 27
@@Eat_Pi THANK YOU SO MUCH

god bless you pe causa
So happy to help 🙏
Not a fan of this method but yes it is fast just maybe a bit too fast for me
Totally fair! There's several different ways you could solve this so any method you're comfortable with is totally good 👍

I did not under stand
I'm sorry to hear that! Is there a certain problem you need help with? There's many different ways you can simplify exponents.
Good sir
I'm glad you think so!
But why switch the 9^3 to the 3 NM I think I got it your making the exponent the same. 😂. Bad math mom here 😅

well i hate maths tysm
lmao you're welcome :D
(2 to the power 5) x (7 to the power 9) = ?
2, 5, and 7 are all prime numbers so there's no real clean way to simply it since prime numbers are only divisible by 1 and themselves.
After flipping 3^3]^2= 27]^2 it's not equal to 9
You're right, but I never said it was. I said they're both equal to 3⁶. And since they're both equal to 3⁶, we can move their exponents around 👍
What...?
😢
