A certain type of bacteria, given a favorable growth medium, doubles in population every 6.5 hours. Given that there were approximately 100 bacteria to start with, how many bacteria will there be in a day and a half?

bacteria double every 6.5 hrs

ryt

so

after 6.5 n hrs ......bacteria are100x 2^n

now for a day n a hlf

hrs =36

6.5n=36

n=36/6.5=72/13

now

bacteria =100x 2^(72/13)

rest can be done frm calculator ..lolz
