    Help needed simplifying the following:

    So I'm struggling with this problem and wondering if anyone could walk me through it so I can figure out how it works.

    y^8 * z^2
    y^-3 * z^0.5

    Help would be appreciated.

    Edit: Just in case the above isn't clear, it's: (y^8 * z^2) / (y^-3 * z^0.5)

    \frac{y^8z^2}{y^{-3}z^{0.5}} = y^{8 + 3}z^{2 - 0.5}

     = y^{11}z^{1.5}

     = y^{11}\sqrt{z^3}.

    Thanks very much, I was almost there myself that last step just stumbled me, probably because when I was going through it I changed Z^0.5 for Sqrt(Z) then got myself confused over the rules.

    For some reason I was thinking it was more complicated than that.

    +rep and thanks for you.
