Rewrite the expression $\frac { 3 w ^ { 3 } } { 5 z ^ { - 3 } }$ using only positive exponents. Assume that z is not zero.
A) $\frac { 27 w ^ { 3 } z ^ { 3 } } { 5 }$
B) $375 w ^ { 3 } z ^ { 3 }$
C) $15 w ^ { 3 } z ^ { 3 }$
D) $\frac { 3 w ^ { 9 } z ^ { 9 } } { 5 }$
E) $\frac { 3 w ^ { 3 } z ^ { 3 } } { 5 }$

We can rewrite the expression as $\frac{3w^3}{5}\cdot z^3$. Since z is not zero, we can rewrite it as $\frac{3w^3z^3}{5}$. This matches with choice E.
