$x^{\frac{1}{2}} = \sqrt{x}$

Step 1

Since the radical is on the right side of the equation, switch the sides so it is on the left side of the equation.

$\sqrt{x} = x^{\frac{1}{2}}$

Step 2

To remove the radical on the left side of the equation, square both sides of the equation.

${\sqrt{x}}^{2} = {(x^{\frac{1}{2}})}^{2}$
