Presentation Transcript

  1. Logarithm

  2. Terms • base • exponent (Ex) 5·5·5 = 53 • exponential form: ax = y (Ex) 53 =125 • logarithm form: logay = x (Ex) log 5 125 = 3 • common log: log10y =x (the base is 10) exponent base

  3. Practice • Find the value of x • 3x = 81 • x3 = 125 • 2-3 = x • log1010 = x • logx0.25 = -2 • log4 x = 2

  4. Problem with log • log 10 = 1 • log 100 = 2 • log 50 = ? • Using a calculator, use the “LOG” key!
