  1. Day 1 : Laws of Exponents Review Book sections 7.1 and 7.4 a0 = 1 b-1 = (am)(an) = am + n = am–n (ab)m = ambm

  2. Do not copy: Objective: TLW • Simplify radicals • Simplify with rational exponents • Find missing side lengths of special right triangles

  3. Roots and Rational Exponents New Law: Rational Exponents If Then = 3

  4. Roots and Rational Exponents New Law: Rational Exponents You may choose whether to find the root or the power first! If Then

  5. Simplify Exponents with Fractions 4 1. 2. 3.

  6. You try on your marker board The teacher will show you 10 problems on the smart board. The student will rearrange the form of the equation from: Exponential to Radical or Radical to Exponential on the student’s marker board.

  7. Everyone to marker board and work with your number partner Convert from Exponential to Radical (marker board)

  8. Convert from Radical to Exponential (marker board) Don’t simplify anything!

  9. Back to Notes: Simplify ExponentialsAssume all variables are positive 4. 5. 6. 7.

  10. Simplify Radicals 8. 9. 10. 11. 12.

  11. Practice Laws of Exponents 13. 14.

  12. More Simplifying with exponentsAssume all variables are positive 15. 16. 17. 18.

  13. 30-60-90 Right Triangle 60° 10 60° 5 2x X 6 60° 3

  14. 45-45-90 Right Triangle 5 X 5 6 X

  15. Do you Get It? EVENs to your marker board and do #1-5! THEN ODDs to your marker board and do #6-10!

  16. Extra Practice on HW 7.1: Work this out in your math notebook. Assume all variables are positive.

  17. Extra Practice on HW 7.1: Work this out in your math notebook. Assume all variables are positive.
