Incorrect. Change radical equations into exponential equations, and then use the fact that $\displaystyle{{b}}^{{y}}={x}\usepackage{cmbright}\Huge\$ is equivalent to $\displaystyle{\log}_{{{b}}}{x}={y}\usepackage{cmbright}\Huge\$ . Identify the values of the variables in the exponential equation and substitute them into the logarithmic equation.
