Derivative of Exponential/Log Function (combined)

[BioBabe91]

Homework Statement

Find the derivative of p = 2log₃(5^s)-log₃(4^s)

Homework Equations

for y=log_b(g(x)), y'=g'(x)/(g(x)ln b)
for f(x)=b^g(x), f'(x)=b^g(x)ln b(g'(x))

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.
