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

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: \(\huge \frac{\sqrt{a}}{\sqrt{b}}=\sqrt{\frac{a}{b}}\)

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.
