Derivative of Exponential/Log Function (combined)

  1. Mar 30, 2009 #1
    1. The problem statement, all variables and given/known data
    Find the derivative of p = 2log3(5s)-log3(4s)

    2. Relevant equations
    for y=logb(g(x)), y'=g'(x)/(g(x)ln b)
    for f(x)=bg(x), f'(x)=bg(x)ln b(g'(x))


    3. The attempt at a solution
    I got to the following: p' = 2*[tex]\frac{5^{s}ln5}{5^{s}ln3}[/tex]-[tex]\frac{4^{s}ln 4}{4^{s}ln 3}[/tex]

    EDIT: Never mind, I just solved it. :D Please close/delete.
