    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
