For this question I'm just going to use / as a square root sign because I don't know how to do it on a computer. Anyways...

So you have /45

Now you have to find a factor that is also a perfect square which is 9 (because 9x5=45)

So you now have /9x5

Since 9 is a perfect square (/9=3)

You can re write it is 3/5 which is the answer
