Copy homework assignment into planner. • Use a white board to complete any bell work that is assigned.

  2. BELLWORK Match the following equations with the correct property: • 1)wy = yw a)Associative Prop of Add • 2) 2(xy) = (2x)y b)Commutative Prop of Mult • 3) (7 + 6t) + 2r = 7 + (6t + 2r) c) Commutative Prop of Add • 4) 5w + 2w +10 = (5w + 2w) +10d) Associative Prop of Mult

  3. Lesson 7: Properties of Exponents 8/21/15

  4. STUDENT OUTCOME The student will….recall and use the Rules of Exponents to simplify expressions. Homework: Worksheets - “What Was Unusual About the Horse-breeding Magazine” AND “What Happens to a Dog Who Eats Table Scraps?”

  5. PRODUCT RULE- When MULTIPLYING with LIKE BASES, you keep the base and add the exponents. QUOTIENT RULE - When DIVIDING with LIKE BASES, you keep the base and SUBTRACT the exponents .

  6. POWER RULE - When RAISING A POWER TO A POWER, you MULTIPLY the exponents. NEGATIVE RULE - When you have a NEGATIVE exponent, you make it a fraction, flip it, and make the exponent POSITIVE.

  7. POWER OF A PRODUCT - When you RAISE A PRODUCT to the same power, apply the power to EACH factor then simplify. POWER OF A QUOTIENT - When you RAISE A QUOTIENT to the same power, apply the power to EACH factor then simplify.

  8. ZERO EXPONENT - When you have ZERO as an exponent, the answer is 1! ALWAYS
