Question 74151: The directions say "Write in simplest form WITHOUT negative or zero exponents"
The problem is (3 times 5) to the negative first... you would think that this meant it would be -15... but I'm not allowed to have a negative answer... using this equation, a to the negative n = 1 over a to the n, it would give you the answer 1/15, but -15 and 1/15 are two totally different numbers... can you help me?
