I had a problem similar to this one. Write expression as a logarithm of a single quantity and then simplify if possible. (1/4)[log (x²-1)-log (x+1)]+3log x Please show the steps.

Hello, Originally Posted by dc52789 I had a problem similar to this one. Write expression as a logarithm of a single quantity and then simplify if possible. (1/4)[log (x²-1)-log (x+1)]+3log x Please show the steps. Note that x>0 and |x|>1, so x>1. Otherwise it is not defined. notice that x²-1=(x-1)(x+1) So now it depends on how you want it to be simplified.
