OpenStudy (binary3i):

\[a=\sqrt{a}^2\]

OpenStudy (binary3i):

\[a/\sqrt{a} = \sqrt{a}^2/\sqrt{a}=\sqrt{a}\]

OpenStudy (kropot72):

\[\frac{a}{\sqrt{a}}=\frac{\sqrt{a}\times \sqrt{a}}{\sqrt{a}}\]

OpenStudy (anonymous):

one way to see it is to square both and see that you get \(a\)

OpenStudy (anonymous):

\((\sqrt{a})^2=a\) and also \((\frac{a}{\sqrt{a}})^2=\frac{a^2}{a}=a\)
