log A + log B = log (AB) log A − log B = log

log A = n(log A) Exponential Growth and Decay
Exponential Growth
Exponential Decay
a(t) = value after t time periods
a(t) = a(0)đ?‘’
a(0) = value at time zero (initial value) k = rate of growth / decay, per time period
a(t) = a(0)đ?‘’
t = number of time periods
