12. A culture of bacteria in the lab doubles every 6 minutes. Assume the growth follows a continuous exponential model and you start with only 2 bacterium.
Using an appropriate exponential base, if this pattern continues to be applicable, find the time in
which the number of bacteria would reach 109. (Round to the nearest minute.)
