good job but heres my solution to this problem ((1+√5)/2)^12=((1+√5))^12/2^12=(((1+√5)^2)^2)^3/2^12=((6+2√5)^2)^3/2^12=2^6((3+√5)^2)^3/2^12=((3+√5)^2)^3/2^6=(14+6√5)^3/2^6=2^3(7+3√5)^3/2^6=(7+3√5)^3/2^3=(343+441√5+945+135√5)/2^3=(1,288+576√5)/2^3=161+72√5 which is the same answer how do you feel about this answer

So that's a percentage trick. How would you do it without a trick😢

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

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

That's how I did it too. Quicker and easier.

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

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

Text: What % of 75 is 15 Symbols: x% of 75 = 15 or (x/100) × 75 = 15 Now make x subject x = 1500 ÷ 75 x = 20
let's walk the long way.. lol
4. ....just a guess

a=8 b=-9 8*8- (-9)=64+9=73 (-9)*(-9)-8=81-8=73

I'm currently on calculus 2, and just now I see the true step by step of an ecuation like this. Great job!

( 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.
