Do you mean $$\huge \frac{\sqrt{50}}{3\sqrt{15}}$$ ?

2. anonymous

yes

Okay, well there are some nice square root rules that let us rewrite a problem like this. First rule: $$\Large \sqrt{a}*\sqrt{b} = \sqrt{a*b}$$ Second rule: $$\huge \frac{\sqrt{a}}{\sqrt{b}}=\sqrt{\frac{a}{b}}$$

alright so now what

We'll use the first rule to split the top up. We want to break it into two things, and we want one of those things to be a perfect square.

so how do you do that
