P.S.  If you need more help with the Laws of Exponents, I have a pretty good explanation on my website at "www2.seminolestate.edu/rrapalje".  If you find this page, then choose the link from my Homepage "Basic, Intermediate, and College Algebra: One Step at a Time."  Choose "Basic Algebra", and look in Chapter 2 for Sections 2.12 and 2.13 on the Laws of Exponents.  I think you will find it "user-friendly" and MUCH easier to read than traditional textbooks.  It's all FREE.
