Dividing Monomials

  • To divide one monomial by another one, use the following properties of exponents:
  • am ÷ an = a m–n, (a ÷ b)m = am ÷ bm, a0 = 1 for any nonzero number a, and a–n = 1 ÷ an for any nonzero number a.
  • An expression is in simplified form if it has only positive exponents.
  • You will often be asked to convert a given expression into simplified form
