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{{a}}^{{n}}{{b}}^{{m}}={{b}}^{{m}}{{a}}^{{n}}\usepackage{cmbright}\Huge\$ . Try simplifying the first expression, then the second expression, and then multiply the terms together.
