C20√6

Good one.

That's not right at all, an easy way to think about it is that the square root and the square cancel it on all of them. The answer is 140

80 = %40 80×2= 160 160 = %80 80÷2 = 40 %40 ÷ 2 = %20 200 = 100% :)

Nice

how abou 2^20+2^20+2^20. ??

-2 is also a root of 4

Or simply 3^44

B. II only. Easy, don’t even need algebra with only 2 options. Just ran both scenarios in my head. A 5th grader should be able to solve

I guess spelling is not an entrance criterion for MIT

Thanks a lot sir❤

Thanks a lot sir. For last question it could also be solved by multiplying 85x2 then divide by 10.❤

Thanks alot sir!❤

SWEET

This is the hardest sat questions!😂 that’s our average gcse question lol

А теперь внимание, вопрос, господа знатоки. Где закономерность плюсования чисел к сотням и десяткам. Вот к примеру 657÷9. Ннннн, давай, складывай.

Thanks. I was bewildered at first because I couldn’t see the tiny negative sign before a^x

Nice one.

Great I can get into MIT now. Where do I i sign up?

A common divisor is 6. Therefore we can consider the number 6 as 100%. 30 is 500%, 24 is 400%. 24 is 4/5. Now, apply this to the number 100. 1/5 of 100 os 20. 20×4 is 80.

what if (x^3+b^2*y)=0?

Yes

Bro 24/30 = 8?💀💀💀 It should be ⅛ which is 80% bc 8/1 is 800%

Ty for teaching a lil

Or you can take 10% of 50 and multiply by 6. Much easier.

Nice

Well done!

Well done

I think that dividing the shape into 3 triangles would be faster, as the sum of a triangle’s angles is 180. So 3 triangle times 3 equal 540

you could also label this as x1 ^ (sin x2), take the exterior derivative and relabel them back to x

Ur going backwards?

😮😮😮😮, cool video mate. Can you explain it further?

I would rather solve this quicker by thinking slightly more before you expand. Observe that in the expanded polynomial, x^2 term can be only achieved by having ax * (-bx) and 3 * 5x. No other combination of terms can have x^2 term. Then the coefficients are as follows -ab + 15 = -9 Thus, ab = 24. Instead of simply wasting your time expanding the entire equation (which is not wrong), you can save more time to solve different problems. Think before you have dive into the problem!

bro i have not done sats yet but I can do that in my brain how do people struggle with geometry?

Cool

-.5?

The 1st answer is not correct, I'm really sorry to tell you that, Im a math professor

General case requires lambert w function

Cool problem and explanation.

That’s fun
