I briefly covered a couple of the laws of exponents a while back, but now that I have access to LaTex, I want to start over again and present them all in a series. So, here we go.
Rule #1- (ax)(ay) = ax+y
Practically: (x3)(x5) = (x * x * x) (x * x * x * x * x) = x * x * x * x * x * x * x * x = x8
Put more simply: (x3)(x5) = (x3+5) = x8
Please note this rule only applies if the base is the same in both terms.
