\frac{\frac{1}{\sqrt{5}}\sqrt{x}\sqrt{5}}{1}=\frac{2\sqrt{5}}{1}
Divide both sides by \left(\sqrt{5}\right)^{-1}.
\sqrt{x}=\frac{2\sqrt{5}}{1}
Dividing by \left(\sqrt{5}\right)^{-1} undoes the multiplication by \left(\sqrt{5}\right)^{-1}.
\sqrt{x}=2\sqrt{5}
Divide 2 by \left(\sqrt{5}\right)^{-1}.
x=20
Square both sides of the equation.
