  1. Is the -3/2 supposed to be an exponent? If so, precede it with a ^ symbol.

    Hint: 25/16 = (5/4)^2

    You should end up with 3 Log(4/5)

  2. Wouldn't that be a decimal answer. Oh, and yes -3/2 is an exponent.

  3. The answer, if turned into a number, will be a never-ending decimal. It's called an irrational number. I doubt if they want you to calculate it out to a lot of decimal places. You have also not specified the base of the logarithm. You'd have to do that to get a number
