    9th Derivative tricky problem

    Find the 9th derivative of (x^8 *lnx)

    -There has to be some other way to solve this besides taking the derivative 9 times... like a pattern or something. But I cannot figure it out. Help please!

    If I were you, I would write out the first three derivatives.
    There should be a pattern there.
