Exponential

Logarithmic
INVERSE
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.
PROPERTIES OF LOGS-- NOTES
1) logb mn = logb m + logb n
2) logb m = logb m – logb n
n 3) logb mp = p logb m
