8.4 Exponents

  1. 1. Algebra warm up: pg. 395 # 64 to 68
  2. 2. 8.4 Negative and Zero Exponents pg. 390 to 395 So yesterday you learned: When dividing like bases you subtract exponents and divide the coeffiecients. ALSO when a fraction is raised to a power--the exponent outside the ( ) gets disributed to the top and bottom the the fraction inside!
  3. 3. Fifth rule of exponents: Negative exponents: DON'T forget all the past rules still apply- ONLT NOW- what happens if your exponent in negative? First try to simplify. If you STILL have a negative exponent-- You have to quot;flipquot; the base and exponents position. If on top--it moves to bottom and exponent turns positive If on bottom--it moves to top ans exponent turns positive.
  4. 4. pg. 391
  5. 5. Try this pg. 391
  6. 6. Sixth rule of Exponents: ANY variable, monomial, constant raised to the power of 0 is ALWAYS = to 1
  7. 7. What if they combine rules on you? You have to know which to do first!!
  8. 8. pg. 392
  9. 9. pg. 392 In a nutshell: ALSO: -Even exponents yield positive answers -Odd exponents yield negative exponents -Negative exponents--change position of the base and change exponent to positive -Zero exponent = 1 EVERY TIME
  10. 10. pg. 393 # 6-17
