k... so...
How do you simplify these when they are in fraction form.
1. A radical over a radical
2. A radical over a non radical
3. A non radical over a radical?
All help greatly appriciated!

Hello,
Be careful for this one
If you have $\displaystyle \sqrt{ab}$, it isn't necessarily equal to $\displaystyle \sqrt{a} \sqrt{b}$.
Because a and b can be both negative.
$\displaystyle \sqrt{ab}$ will be defined, but not $\displaystyle \sqrt{a}\sqrt{b}$
For example, let's take a=-2 and b=-3.
$\displaystyle \sqrt{ab}=\sqrt{(-2)(-3)}=\sqrt{6}$
But $\displaystyle \sqrt{a} \sqrt{b}=\sqrt{-2} \sqrt{-3}$
Which is... weird
