Answer
$c^\frac{1}{2}$
Work Step by Step
We are asked to replace radicals with exponents in the given equation:
$\sqrt[4]{c^2}$
Recall the rational exponent property (pg. 382):
$a^{\frac{m}{n}}=\sqrt[n]{a^m}=(\sqrt[n]{a})^m$
Applying this property, we get:
\begin{align*}
\sqrt[4]{c^2}&=c^{\frac{2}{4}}\\
&=c^\frac{1}{2}
\end{align*}
