Work Step by Step

Simplify the expression $\sqrt{8}-2\sqrt{2}+\sqrt{12}$, $\begin{align} & \sqrt{8}-2\sqrt{2}+\sqrt{12}=\sqrt{4\times 2}-2\sqrt{2}+\sqrt{4\times 3} \\ & =2\sqrt{2}-2\sqrt{2}+2\sqrt{3} \end{align}$ Subtract the like terms, $\sqrt{8}-2\sqrt{2}+\sqrt{12}=2\sqrt{3}$ Thus, the expression $\sqrt{8}-2\sqrt{2}+\sqrt{12}$ can be simplified as $2\sqrt{3}$
