The Attempt at a Solution
OK so for number 1 I do not know where to start.
For number two I factor it and I'm in the same spot as number 1.
As far as number 3 is concerned I do not know where to start.
Number 4 I know that I have to condense the logarithms into one but I'm not sure what to do afterwards.
