8.2 Exponenrts

  1. 1. Algebra Warm Up: pg. 382 # 68-69 REMEMBER --becasue of the ABS value-- split into 2 cases to solve!
  2. 2. 8.2 Laws of Exponents: Powers and Products pg. 377 -382 So yesterday you learned: When multiplying like bases--you add exponents When multiplying monomials--you multiply the coefficents, add the exponents of the like bases
  3. 3. The second rule of exponents: (3 parts) Raising power to a power. In this case you will be applying an exponent to a set of parentheses (multiplying the exponents together)
  4. 4. pg. 378
  5. 5. Raising Monomials to a Power In this case--again you are applying the exponent outside the ( ) to everything inside! JUST like you use Distributive Property--The exponent applies to EVERY part inside the ( )--THEN simplify if you can!
  6. 6. pg. 379
  7. 7. pg. 379
  8. 8. pg. 380
  9. 9. Sometimes you will have word problems--This just involves SUBSTITUTING an expression into a formula
  10. 10. Powers of -1 Recall from chapter 2- negative x megative = positive negative x positive = negative positive x negative = negative positive x positive = posistive This idea applies to exponents and negative numbers! EVEN exponent applied to negative bases GIVES positive answer (negatives cancel out) ODD exponent applied to negative bases GIVES negative answer
  11. 11. pg. 380
  12. 12. Now you try them together! pg. 381 # 2-25 DON'T forget about the rule from yesteday--They will still apply!
