<prompt> A bacterium can divide every 20 minutes. Beginning with a single individual, how many bacteria will be there in the population if there is exponential growth for 3 hours:184405121024  <response>: P C I rnWhere, P Final valueC Initial valuer fraction increasen no. of times increaseIn the given question, A bacterium can divide every 20 minutes and exponential growth is for 3 hours,Thus, C 1,And r 1 it doubles every timen 3 hours20 minutes 9 timesThus P C 1 1 1 19 29 512One Oilier Simple Way of Doing ITGiven information: A bacterium can divide every 20 minutes 3hourThus in 3 hours, it will total divide 3hour x 3 hours 9 timesThus 9 times multiplication will successively yield 2, 4, 8, 16, 32, 64, 128, 256, 512 bacteria.So at end of 9 hours, there will be 512 bacteria.
