Quotient Rule Involving A Logarithm

The problem is:

By doing the quotient rule I get: and and and

When I apply the quotient rule I get: g'(x) = (10 - ln 4 log_4 x)/(x^2 ln 4) (sorry, I couldn't figure out the latex for this part.)

This answer is not even remotely close to the actual answer in the book. What did I do wrong?

note the change of base formula ...
