neil was growing a culture of bacteria for a biology experiment. he noticed that the population doubled after 90 minutes. if the population grows exponentially, how many times the original population will there be after six hours?

Looks like base 2 numerals:
90min. = 1.5h,
6h / 1.5h = 4.
Po = 2^0 = 1 = Initial pop.
P = 2^4 = 16 times Po.
