Exponent Rules

Today we discussed the three exponent rules that everyone should know: the multiplication rule, the power rule, and the division rule.  When multiplying with exponents, we multiply the bases (big numbers) and add the exponents of like terms. When multiplying with exponents on the outside of parentheses, put your bases to the power of the outside exponent and multiply your exponents inside with the one outside. When dividing with exponents, divide the bases and subtract the exponents.

Note: if you get a negative exponent when dividing, change it to a positive exponent by putting it in the denominator.
