Multiply and simplify. Assume that all expressions under radicals represent positive real numbers.

$\sqrt[6]{(z - 7)^{4}} \sqrt[6]{(z - 7)^{32}} = \text{ }$
Write your answer using radical notation if necessary.

Help: To enter the square root of a number use sqrt(). For example, to give $\sqrt{7x}$ as an answer, you would type sqrt(7x). If you mistakenly type sqrt 7x instead, Webwork will take this to mean $x \sqrt{7}$, not $\sqrt{7x}$. That is, you MUST put parenthesis around everything that you want to take the square root of.
