Question 328182: Please help me solve this: (2x^7y^2/4xy^3)^3
I do not even know where to begin.
I am studying for the college placement test and I have the answer for it but I can not figure out how to get that answer. I have tried many different things and my answer does not come close to the actual one.

You can put this solution on YOUR website!
Begin with the laws of exponents.
x%5E%28a%29%2Ax%5Eb=x%5E%28a%2Bb%29
x%5Ea%2Fx%5Eb=x%5E%28a-b%29
%28x%5Ea%29%5Eb=x%5E%28a%2Ab%29
x%5E0=1
%28xy%29%5Ea=x%5Ea%2Ay%5Ea
Those are the only things you need.
