Im taking Business calc so it's not nearly as hard as normal calc, and I have a few questions on a take home quiz I have. If any one could help me it would be greatly appreciated.

Find the derivative, do not need to simplify

g(x)=ln(2x-3/x^2-4)

and f(x)=(ln(12x^2+5))^25

lastly y=e^x ln(5x)

Thanks a lot, im pretty much done with the quiz im just not sure on these 3 probs (Headbang)
