we used three of the Rule of Exponents, along with the Distributive Property to simplify expressions. Remember that
when you:
a) multiply two powers having the same base, you add the exponents.
b) find a power of a power, you multiply the exponents.
c) find a power of a product, you find the power of each factor and then multiply.
