    Think of it as x3/2 * x-1

    Re: Fractional Indicies
    x^a / x^b = x^(a-b) - that's a standard result. Can you go from there?

    Your answer x^5 is correct. So use the same method for your question.

    Isn't the sum one and a half subtract one.

    x^{1.5-1}=

    1.5=\frac{3}{2}

    \frac{2}{2} = 1 \ \ so \ \ \frac{3}{2} - \frac{2}{2} =

    May be you also need to add that  \dfrac21 = 2

    You got it right here.

    xa / xb = xa-b.

    x3/2 / x.

    x = x1 = x2/2.

    x3/2 / x2/2.

    = x1/2.
