  1. 8.3 Division Properties of Exponents Learn to use the division properties of exponents to evaluate powers and simplify expressions.

  2. Focus 8 Learning Goal –(HS.N-RN.A.1 & 2, HS.A-SSE.B.3, HS.A-CED.A.2, HS.F-IF.B.4, HS.F-IF.C.8 & 9, and HS.F-LE.A.1)= Students will construct, compare and interpret linear and exponential function models and solve problems in context with each model.

  4. am an Rules for Division Let a and b any real number, and m and n be integers. Quotient of Powers Property: Subtract n from m (a0) = am-n

  5. m a am b bm Rules for Division Power of Quotient Property: Distribute power across the ( ). = *Remember: a negative exponent means to rewrite its reciprocal!!
