For more detailed explanation for the topic of LAWS of EXPONENTS, see my website, by clicking on my tutor name "rapaljer" anywhere in algebra.com, and look for my first link:  "Basic, Intermediate, or College Algebra: One Step at a Time."  Go to Basic Algebra, Chapter 2, Section 2.12 Laws of Exponents.  I think you will find this a much simpler explanation than what they give you in the traditional textbooks.
