A certain strain of bacteria divides every four hours. If a colony is started with 10 bacteria, then the time t (in hours) required for the colony to grow to N bacteria is given by
t = 4(log(N/10)/log2

Find the time required for the colony to grow to one million bacteria. (Round your answer to two decimal places.)

N=1000000
you plug this number into the equation like shown below
4(log(1000000/10))/log(2)
log(1000000/10)=5
log(2)=.301029
4(5/.301029)=66.4387
the answer is 66.44 if you round it to two decimal places.
I hope this helps :)))
