Thank you for your support of my videos!

Hi, I am glad to see that you have tried to work this out. However, you made an error. Please try again and watch the video till the end to check your answer!

@MathEnabler yes .Thank you.

@MathEnabler I did not take highest cube less than 804.It is 9^3 not 8^3.Rest is ok.

Very good!

Good! You got it right! Watch the rest of the video for the other questions and see if you can also get the rest right. Thank you for watching my videos!

@@MathEnabler Actually I don't watch your videos, I just do the sums!

​@@susangratwick5327 Thanks for the clarification. I hope you will watch my videos someday! Have a good week!

Thank you very much for your feedback! I am glad that you like the video and find it useful!

Hi, it does work with 24: Choose square root of 25, which is 5. Take 5 x 2 which is 10 as the denominator. Then, take 24-25 which is minus 1. Then take 5 - 1/10 which is 4.9. This is a special case, as 24-25 becomes a negative number. Hope this helps. Feel free to let me know if you have any more queries!

Hi, I am glad that you like the video! I appreciate your support!

But diffrent

Thank you so much for explaining the binomial approximation as the basis for this fast shortcut method of computing the square root of a number.

Yes, you are right! In this method, you multiply the square root of the perfect square by 2 to get the denominator.

Yes, for this algorithm, you times 2 to get the denominator.

Hi, thank you for your interest in my channel. Do you mean you want to know more about denominators? I have a few videos on how to add and subtract fractions with like and unlike denominators. You can watch them here: www.youtube.com/@MathEnabler

Glad you like it!

I am glad to hear that my video has helped you to understand how to add fractions with unlike denominators. My other math videos are available here: m.youtube.com/@MathEnabler Do watch them too and let me know your feedback on them. I hope they will be of help to you too!

Thank you for your compliment!

Hi, 2 is not common multiple for 8, 12 and 6. 2 is a common factor of 8,12 and 6 but not a common multiple.

Well you could rewatch it over and over until you get it

Glad it helped!

Hi, this video is on subtracting fractions. Thank you!

​@@MathEnablerso if I ask you add 5-2 what is your answer

5 -2 ___ Subtract. My answer is 7. What's your answer

Idk how old 8th grade is but in Singapore we learn this at 13

@@Jenjenson0 8th grade is 13 or 14

​@@Jenjenson0clarification: we were indeed given tools to solve this at 13/14 but i doubt most sgporeans wld be able to solve this if you picked one out at random. but yeah maybe at most theyll ask us to find x^2 + y^2 from this in an exam question.

@friepima499 That's true, you probably wouldn't see a question like this in sec 1 so the average student may not be able to solve it. While I don't recall my sec 1-2 exams I know that there are similar questions in the earlier sections of O level papers, which are the easier ones that test sec 1-2 concepts. If you pick out a sec 1 student getting As for math which isn't difficult, they'd probably be able to solve this though

@@friepima499 You're right. I solved x²+y² question in a real study book.

That's the thing, we don't need to know

You only answer what's asked

you can solve for x by getting y from the first formula, and using it in the second. I.d., x + y = 12 -> y = 12 - x | xy = 10 -> x(12 - x) = 10 -> 12x - x² - 10 =0 -> x ≈ 11.1 or x ≈ 0.9
