7. What are monomials ? CFU NAME_________________________ PERIOD ____ 10.22.13 Monomials are terms that are constants such as integers, variable terms, or the product of a number and one (or more than one) variable. Exponents apply to only to the base term, unless the monomial is grouped with parenthesis. Exponent Rules such as Product Rule, Quotient Rule, and Power Rule apply to the base number only, not the Coefficient.
