# How do you simplify (6/z^4)^3 and write it using only positive exponents?

Sep 1, 2016

$\frac{216}{z} ^ 12$

#### Explanation:

You have cube everything in the bracket.
(multiply it by itself any by itself again.)

${\left(\frac{6}{z} ^ 4\right)}^{3} = {6}^{3} / {z}^{4 \times 3}$

=$\frac{216}{z} ^ 12$
