  1. Grade 10 Academic MathReview Day 2 Exponent Laws Wednesday, September 4th, 2013

  2. Agenda • Take up homework • Exponent Laws • Product rule • Quotient rule • Power of power rule • Practice

  3. Learning Goal By the end of the lesson… … students will be able to multiply and divide powers with the same bases using the product, quotient and power of power rules, including those with negative or zero exponent outcomes

  4. Curriculum Expectations • Course – not applicable (prior review) • Ontario Catholic School Graduate Expectations: The graduate is expected to be… a self-directed life long learner who CGE4f applies effective… problem solving… skills

  5. Mathematical Process Expectations • Problem solving – select, (and) apply… a variety of problem-solving strategies

  6. Exponent Laws • Product Rule – when multiplying powers with the same base, add the exponents and write the product as a single power • Ex. (x2)(x3)

  7. Exponent Laws • Quotient Rule – when dividing powers with the same base, subtract the exponents and write the product as a single power • Ex.

  8. Exponent Laws • Power of Power Rule – when you have a base with an exponent, all to another exponent, you keep the base and multiply the exponents • Ex.
