B.
1. how did you simplify each expression above?
2. what do you hink would make it easy, to simplify the given expression?why?

When multiplying terms, you add the exponents. when dividing terms, you subtract exponents. With exponents of exponents, you multiply. For example,
3. (3^2)^3 = 3^2 * 3^2 * 3^2 = 3^6
