    8 4 Negative And Zero Exponents 8 4 Negative And Zero Exponents Presentation Transcript

    • Negative and Zero Exponents Algebra I Chapter 8.4
    • Negative Integers do NOT mean negative numbers
    • Numbers to the Zero Power
      • Every number to the Zero Power, such as 5 0 = 1.
      • We can use last lesson’s division of powers as a proof.
    • Using division to prove
      • Any number divided by itself equals 1.
      • Using the Quotient of Powers Property, the exponents would be subtracted.
      • 6 5-5 = 6 0 = 1
    • Negative Exponents
      • Negative Exponents do not mean negative numbers.
        • 4 -5 =
        • 3 -2 =
        • 7 -4 =
    • Solve.
      • c -4 * c 4
      • d 4 f 3 = d 4-6 f 3-3 =d -2 f 0 =
      • d 6 f 3
    • Simplify.
      • b 6 *b -2 =b 4 = 1
      • b 4 b 4
      • -3y -2
      • -6p -7
      • 8a 4 b 7 c -4
      • 3a 6 b -6 c -4
    • Simplify.
      • - 3y -2 = -3
      • y 2
      • -6p -7 = -6
      • p 7
      • 8a 4 b 7 c -4 = 8 a 4-6 b 7--6 c -4--4 = 8 b 13
      • 3a 6 b -6 c -4 3 3 a 2
      • ** (c 0 =1 which when multiplied is no longer part of the answer.
