Incorrect. Rewrite the equation as an exponential equation: $\displaystyle{{8}}^{{3}}={2}{{x}}^{{2}}\usepackage{cmbright}\Huge\$

Simplify and then solve as you normally would to isolate the variable x. Doing this, you get $\displaystyle{x}=\pm{16}\usepackage{cmbright}\Huge\$ . The correct answer is 16.
