    Yeah, 5/9 is way too big. Do you only need x-bar and not y-bar?

    Is this what you started with? \[\huge x-bar=\frac{\int x^{5/4} dx}{\int x^{1/4} dx} \]

    The limits of integration are from 0 to 1 I believe.

    Well the curve on the top is technically y=1.

    I think you need to switch x and y to find x-bar and y-bar. i.e. for x-bar it is integral of y dA, and for y-bar it is integral of x dA.
