Homework Help: Quick n easy derivative question

  1. Apr 21, 2010 #1
    I'm trying to study for my final on friday from past exams and their keys, and one question is the integral of 3x+3x

    I get through it all fine, but then according to the key, the derivative of 33x is just (ln3)(3x)

    so here's my question, I thought that by chain rule, it should end up being
    (ln3)(33x)(ln3)(3x) shouldn't it?

    What is the question -- 3x+3x or 33x? Assuming the latter, which would usually be parsed as 3(3x) the derivative would be what you have said.
