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*$$\frac{5^{s}ln5}{5^{s}ln3}$$-$$\frac{4^{s}ln 4}{4^{s}ln 3}$$

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