I got the same answer, but I did differently. sqrt( 54^2 - 45^2) sqrt ((9*6)^2 - (9*5)^2) sqrt (9^2 * (6^2 - 5^2)) 9 * sqrt(36-25) 9 * sqrt(11)

9^10 + 9^10 + 9^10 => 3*9^10 => 3*3^20 = > 3^21

Thank you for sharing your information ℹ️

Ingenious ❤

Тяжёлый способ. Лучше представить 54 и 45 как 9* на 6 и 5. Висе сразу получается

I got 1594319... ...I squared 729 what is equal to 3^12 and got me to 531441 and I then multiplied with 3 one final time to just subtract 4... ...not too difficult Le p'tit Daniel

Nice trick

1/2. 0.5 what-evers.

Your math is off! Get a calculator people this man doesn’t know what tf he is talking about !

Good

500 in one shot..,.30 times 5 in 150...French schooling one of the best in the world

I've always liked: 150 = n / 100 × 30. Then just solve for n. Always made so much more sense to me.

4x5 is 20 so the answer is 40%

just use gp

took me 8 seconds

Yes indeed sir.👍🌞

Im so glad I learned the correct way to- this person is delusional

that is nice problem. managed to reduce it to y+y²+y³=155, but didn't think to guess the roots after that

8^9(1+1+1+1)2^3×9×2^2=2^27+2=2^29

75 is 100 % 75/15 = 5 => 15 is 1/5th of 100 100/5 = 20%

x=3.645~

4 and 6

6 minutes to solve that simple problem??

You are going from china is the short road to do that

Only you understand your self!!

( 15! )/( 17! - 16! ) = ( 15! )/15! ( 16 ×17 - 16 ) = 1/16 ( 17 - 1 ) = 1/(16x16) = = 1/( 2^4 × 2^4 ) = 1/( 2^8 ) = 2^( - 8 )

4^11

8^9 + 8^9 + 8^9 + 8^9 = 4 × 8^9 = 2^2 × ( 2^3 )^9 = 2×2 × 2^27 = 2^29

x=4

2exp-8 should have been a more elegant form of the result in my mind.

We solve equations. Are we solving for what or are we simplifying

pls ma do explain how come about the 3

Well explained sir unlike the crap from other videos of the same type❤
