For any number "a" (except zero), a0 = 1. Now I have a homework
problem: Simplify the expression: mn0 So, I put in for my answer
1, but when it was graded the teacher said that that was the
wrong answer. How could it be wrong if any number the the power
if zero is 1? Did I misread my book, or did the teacher's answer
key make a mistake?
