错啦啊
@@jingshen6287 这怎么错了?
Bruh just simple √24 ~ 4.9 Like 4.9² = 24.01 5 - 4.9 = .1 => √ 10/.1 => √100/1 ~ 10 or less then 10 Just simplest way😴
Genius man ☺️ 👍🏻
@@Mb-logic thanks man😎
Towards the end, which you factor out the sqrt(5), you are left with sqrt(6) + 2, not the sqrt(6) + 4 that you show.
Check again your mistake
@@Mb-logic 5:16. moc5541 is right
Good Job ALjabar Mathematics ❤ 😊

1:45 How did yo do that?
I take common a-b (a+b)(a-b)+(a-b) =(a-b)(a+b+1)
@@Mb-logicAre they the same? ((a-b)(a+b)+1)=0 (a-b)(a+b+1)=0
Yes but a is not equal to b.
In answer yo your question, no Anything you want to know ?
Yes
@@Mb-logic Ok, I am only barely literate, and almost completley inumerate, in my simpletons brain, letters of the alaphabet do not play any part in maths. In addition I am also dyslexic and come from a backround where education was an inaffordable luxury. Thanks for your interest, I hope that answers your question.
Ok ☺️
12
7 5 so 12
I don't know why I started with 7x7 -5x5=24 instead of 5×7=35
12. X & Y are 5 or 7. 24=12 x 2, so x+y =12.
👍🏻
7,5 and -7, -5 ezzzzzzzzzz
How to really solve this problem? give me two numbers which multiplied together yield 35. Uhmmmmmmm?: 7 and 5? What is 7^2 - 5^2? Uhmmmmm? 24 ? What is 7+5? Uhmmmmmmmm? 12? Done.
Thanks dear 🥰
Solve via Eq 2. xy = 35. There are four factors 1, 5, 7, 35. Neither 1 nor 35 satisfies Eq. 3, therefore 5 and 7 are the possible answers. Setting x=7 and y=5 satisfies Eq. 1. Does not require 5 pages of work.
Thanks for your information ☺️.
By definition: 2ⁿ - 2ⁿ⁻¹ = 2ⁿ - 2ⁿ/2¹ = 2ⁿ - 2ⁿ/2 = 2(2ⁿ)/2 - 2ⁿ/2 = 4ⁿ/2 - 2ⁿ/2 = (4ⁿ-2ⁿ)/2 = 2ⁿ/2 = 2ⁿ/2¹ = 2ⁿ⁻¹ Even more generally: xⁿ - xⁿ⁻¹ = xⁿ⁻¹(x-1) And even _more_ generally, xⁿ - xⁿ⁻ᵏ = xⁿ(1-x⁻ᵏ)
I did (x + iy)^2 = x^2 - y^2 + 2ixy, substituting the given values gives (x + iy)^2 = 24 + 70i. Taking the square root (using sqrt of modulus and a half-angle formula) gives x + iy = 7 + 5i, so x = 7 and y = 5 and x + y = 12.
Good luck
2^99 is half of 2^100 thatsyall
nice handwriting !
Thanks You ☺️
x-y x+y = 24 and xy =35 so we can assume x=7 and y =5 because 7+5 . 7-5 = 24 so x+y=7+5 and the answer is 12 there weren't. any limitation that x and y are real numbers or cımplex numbers etc so yours and mine are both correct. bless you..
Right 💯

10+10×0-1=9 because 10×0=0+10=10-1=9 😏
Right ☺️

B is correct
Option B:- 9

According to DMAS rule.... (b) 9.
You don't need to fckn name the rule this is 3rd grade math
The rules still apply.😅
@@vickyjohnson7172 ye but imagine you don't know the rule u must live in America or something
Right 💯
Yes ☺️
