$\\sqrt{2x} = 4$

$\\sqrt{2x} = 4$

$\sqrt{2x} = 4$

To eliminate the square root, square both sides of the equation $\sqrt{2x} = 4$. This gives $(\sqrt{2x})^2 = 4^2$, which simplifies to $2x = 16$.

Divide both sides of the equation $2x = 16$ by 2. So, $\frac{2x}{2}=\frac{16}{2}$, which gives $x = 8$.

$x = 8$
