  1. 8-4 zero and negative exponents Algebra 1 CP Objective: evaluate and simplify expressions in which zero and negative numbers are used as exponents.

  2. Zero as an exponent • For any nonzero number a, a0 = 1 • Ex: 50 = (-2)0= (3/2)0= Negative exponents For any nonzero number a and any integer n, Ex: 6-4 = 7–1 =

  3. Example • Write each expression as a simple fraction. • a. 4-3 b. (-3)-2

  4. Try on your own… • 3-4 b. (-7)0 • (- 4)-3 d. 7-3 • e. - 3 -2

  5. Example • Rewrite each expression so that all exponents are positive. • 4yx–3b.

  6. Classwork/homework • Pg382 - 383 # 14 – 36 even, 52, 54, 56
