I have a question from a book I am reading but I am guessing I do not understand it since it makes no sense to me. I understand exponents just fine but I am guessing this is more of a proof question, which I am not so good at.

Prove the given Laws of Exponents for the case in which m and n are positive integers and m > n. Question a) is for Law 2 and the answer it gives is negative. I noticed when searching online that not all the rules coincide exactly, so at least in this book Law 2 is division of exponents - a^m/a^n = a^m-n. I understand the law just fine and how it works, I guess I am just not understanding the question.

Thanks for the help.
