    \frac{2}{3}x^{-4} will integrate to some fraction of


    \frac{2}{3}x^{-3} + c ... what fraction, though?

    If you meant

    \frac{2}{3}x^{4} then some fraction of


    \frac{2}{3}x^{5} + c ... what fraction, though?

    Yeah, that's the first one above...

    \frac{2}{3x^4} = \frac{2}{3}\ \frac{1}{x^4} = \frac{2}{3}x^{-4}
