Homework Help: Sqrt(xy)/y simplification?

  1. Feb 18, 2016 #1
    1. The problem statement, all variables and given/known data
    I just had a simplification question. How is (sqrt(xy))/y the same thing as sqrt(x/y)??

    2. Relevant equations
    none

    3. The attempt at a solution
    I don't see how you can get that. I tried square rooting the top and bottom, but I don't think that gets you anywhere...
