(2/3) to the 4th power.
So I know you have to go 2X4X4X4X4 = 512 I believe
3X4X4X4X4 = 768 I think
What is the easiest way to reduce an equation thingy? I got it down to 128/197 but that was wrong.

actually no.
2^4 = 2 x 2 x 2 x 2
---- ..... ------------------
3^4 = 3 x 3 x 3 x 3
exponent means how many times a number is repeatedly multiplied to itself.
and the answer should be 16/81

It's 16/81
(2/3)(2/3)2/3)(2/3) = 16/81

it's not 2*4*4*4*4 it's 2*2*2*2 / 3*3*3*3 so it should be 16/81 which does not reduce.

For increasing cubic binomials the final formulation is as follows: (a + b) ^ 3 = a^3 + 3*a^2*b^a million + 3*a^a million*b^2 + b^3 on your case, a is x and b is -y^5 So (x - y^5)^3 = x^3 + 3*x^2*(-y^5)^a million + 3*x^a million*(-y^5)^2 + (-y^5)^3 Simplified: =x^3 - 3x^2*y^5 + 3x*y^10 - y^15 :D

2x2x2x2=16; 3x3x3x3=81
Therefore, (2/3)^4=16/81.

2/3 to the 4th power means (2x2x2x2 ) / (3x3x3x3)
It does not reduce.
