Answer
$|x|$
Work Step by Step
$\bf{\text{Solution Outline:}}$
Use the properties of radicals to simplify the given expression, $
\sqrt[6]{x^6}
.$
$\bf{\text{Solution Details:}}$
Using a property of radicals which is given by $\sqrt[n]{x^m}=\left|x^{m/n}\right|$ if $(m/n)$ is odd and $\sqrt[n]{x^m}=x^{m/n}$ if $(m/n)$ is even, the expression above is equivalent to
\begin{array}{l}\require{cancel}
|x|
.\end{array}
