My daughter has the problem: 15 with an exponent of zero=1. Could you help explain why? I would appreciate an answer soon as she has class tomorrow. thanks,

Hi Mike,
The motivation behind the fact that is the rules of exponents, in particular the rule that
whenever a is not zero.

If this rule is be true when b=c then, since

you are forced to say that .

I hope this helps,
Penny and Patrick
