Rationalizing denominator
I just need to understand how rationalized $\frac{2}{\sqrt{2\pi}}$ to get $\sqrt{\frac{2}{\pi}}$

When I rationalized, I just multiplied by $\frac{\sqrt{2\pi}}{\sqrt{2\pi}}$ and got $\frac{\sqrt{2\pi}}{\pi}$

Hey downthesun01.

Hint: 2 = SQRT(2)*SQRT(2) and SQRT(2*pi) = SQRT(2)*SQRT(pi).

Prove It
Re: Rationalizing denominator
The result does not have a rational denominator. It is just a simplification.
