Simplify the following expression, and write your answer using only positive exponents.

$\displaystyle \left( \frac{x^{8}y^{5}z^{3}}{x^{-7}y^{-4}z^{-6}}\right)^{-3}=$

This problem initially looks quite complicated, but as long as you gather each of the variables together and remember your properties of exponents, it’s not as bad as it first looks- honest!
