  1. Bell Ringer (in Math Journal) What are the laws of exponents? 1. xmxn= 2. xm = xn 3. (xy)n = 4. (x)n = (y) 5. x –n = 6. x0 = 7. (x m)n =

  2. Logarithms Monday, April 7, 2014

  3. Graphs • Exponential • Logarithmic

  4. Inverse

  5. Notes The inverse of an exponential function is a logarithmic function. To convert from an exponential to a log –> 25 = 32 is log2 32 = 5 Calculators only do log10 which is called “common log” So log is really log base 10.

  6. Properties of Logs-- NOTES 1) logbmn = logb m + logb n 2) logbm = logb m – logbn n 3) logbmp = p logb m
