<em>Additional comment</em>
I find it easy to remember the rules of exponents by remembering that <em>an exponent signifies repeated multiplication</em>. It tells you how many times the base is a factor in the product.
Multiplication increases the number of times the base is a factor.
Similarly, division cancels factors from numerator and denominator, so decreases the number of times the base is a factor.
