why is a/sqrt(a)=sqrt(a) ? 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 $$(\frac{a}{\sqrt{a}})^2=\frac{a^2}{a}=a$$
