Multiplying Monomials

  • A monomial is a product of a number and zero or more variables. If there are no variables, the monomial is called a constant.

  • A power is an expression of the form xn, where n is a positive integer. The variable x is called the base and the number n is called the exponent.

  • Recall from earlier work the laws of exponents: an· am = am+n, (am)n = amn, and

  • (ab)m = ambm.

  • An expression is considered to be in simplified form if each base is used exactly once, there are no powers of powers, and all fractions are in simplified form.

  • You will often be asked to convert a given expression into simplified form.
