Exponential functions are indicated on typographical material as a small number written on the top right of the base, like:
While this is relatively difficult to do in a post, we usually represent the same expression using straight typing as:
Do not forget the parentheses, because exponentiation takes precedence over multiplication/division.
So please check that the given formula is:
Po=population today, so Po=800.
t=number of months, so t=24 for two years.
There leaves only one unknown,
P=800*(2)^(24/90)=962.4, say 963
b. 90 represents a factor for the rate of exponential growth. The bigger the factor, the slower the population grows.
c. "How long" means we need to find "t".
take log to the base 2:
so t=4*90=360 months = 20 years, assuming the population grows unchecked.
