Incorrect. Be sure to use the exponent rules: $\displaystyle{{\left({{x}}^{{n}}\right)}}^{{m}}={{x}}^{{{n}{m}}}\usepackage{cmbright}\Huge\$ and $\displaystyle{{x}}^{{n}}{{x}}^{{m}}={{x}}^{{{n}+{m}}}\usepackage{cmbright}\Huge\$ . Also, remember that $\displaystyle{{x}}^{{1}}={x}\usepackage{cmbright}\Huge\$ and $\displaystyle\frac{{{x}}^{{n}}}{{{x}}^{{m}}}={{x}}^{{{n}-{m}}}\usepackage{cmbright}\Huge\$ . Use these rules to help you simplify the expression.
