Answer
$\dfrac{x^5}{32}$
Work Step by Step
In order to simplify the expression, we distribute the -5 into the parenthesis. Using the laws of exponents, the given expression, $
\left( \dfrac{2}{x} \right)^{-5}
,$ simplifies to
\begin{array}{l}\require{cancel}
\left( \dfrac{x}{2} \right)^{5}
\\\\=
\dfrac{x^5}{2^5}
\\\\=
\dfrac{x^5}{32}
.\end{array}
