You have to use the correct Mathematica syntax. E and Log instead of e and LN. You don't even have to use Simplif in this case.

I have another question if you don't mind. I'm trying to just check and see if I got a whole bunch of even-numbered study exercises right on exponents and natural logs. The answers to the odds are in the book. As an example, LN(1/e^2) equals what? My answer is -1/2. In mathematica, I tried Simplify[LN(1/e^2)] and it just spit the same thing out as the output. I also tried a couple of variations of Solve[LN[1/e^2] = X] with essentially the same result How would you get Mathematica to verify that the answer is -1/2. Thanks a lot.
