Question 48334: I have this problem, and I have to simplify it and express in terms of positive exponents. (3x^-4y / z^2) All to the power of -3.
The answer I've come up with is x^12 / 27y^3z^6. I'm really not sure about this problem. Thanks.

Simplify:
%28%283x%5E%28-4%29y%29%2Fz%5E2%29%5E-3 = %28z%5E2%2F%283x%5E%28-4%29y%29%29%5E3 = %28%28x%5E4z%5E2%29%2F3y%29%5E3 = %28x%5E12z%5E6%29%2F27y%5E3
