As a consequence of the Chainīs Rule:

Hello.
Could someone explain me the following in the subject of derivative.
y = ln x ; y'= 1/x
Following that rule why doesn't y =ln x^5 equal y' = 1/x^5 but instead y' = 5/x
If someone could explain me this I would be very greatful.
PS! I am not an english speaking person so my english is limited.

The question you are asking here is quite similar to your first question..
Look at FernandoRevilla's suggestion in post #2
where and then find the derivative... show your work f you are stuck...
