Incorrect. Use the rules of exponents: $\displaystyle{{\left({{x}}^{{n}}\right)}}^{{m}}={{x}}^{{{n}{m}}}\usepackage{cmbright}\Huge\$ , $\displaystyle{{x}}^{{n}}{{x}}^{{m}}={{x}}^{{{n}+{m}}}\usepackage{cmbright}\Huge\$ , and $\displaystyle{\sqrt[{{3}}]{{{x}}}}={{x}}^{{\frac{{1}}{{3}}}}\usepackage{cmbright}\Huge\$ . Be sure your answer is in the form c/d where c and d have no common factors greater than 1.
