    • Let’s Divide! Dividing Monomials Chapter 8.3
    • Quotients of Powers
      • How do I find ?
      • a*a*a*a*a*a =
      • a*a*a*a
      • a 2
      • 1 = a 2
      a*a*a*a*a*a = a*a*a*a
    • Let’s find a different way
      • In the previous slide, you saw that the result of this fraction was a 2 .
      • How do 6 and 4 relate to two?
    • Quotient of Powers Property
      • For all non-zero numbers, subtract the exponent of the denominator from the numerator when the bases are the same.
      • 4 5-2 = 4 3
    • Let’s prove it.
      • 4 5-2 = 4 3
    • Try Some.
    • Solutions
      • 2 10-5 = 2 5
      • 3 10-7 = 3 3
      • 5 8-3 = 5 5
      • 2 3-2 = 2 1= 2
    • Try Some with variables.
      • x j-1
      • x a+b-c
      • x m+1-1 = x m

      • -2x 2-1 y 5-3 =-2xy 2
      • -40a 4-1 b2c -5
      • = -40a 3 b 2
      • c 5
    • Remember negative exponents?
      • Any time you have a negative exponent, it must be placed in the denominator.
