    Question Powers/Indices

    Hi All,

    I'm having some problems with this powers/indices problem. I've managed to solve the others (when the letter was same top and bottom, however now I'm stuck!

    Simplify by subtracting indices and dividing or cancellingcoefficients:

    27X5
    18Y5

    (Small numbers are the powers).

    Help! Many thanks.

    If x and y are independent variables, you can't cancel them. However,

    (27x^5)/(18y^5) = (9*3x^5)/(9*2y^5) = (3x^5)/(2y^5)
