A certain strain of bacteria that is growing on our kitchen counter Double Evey 45 minutes. assuming that we start with one bacterium.
To find : how many bacteria could be present at the end of 180° minutes.
solution : The bacteria doubles every 45 minutes.
if we start with only one bacterium.
after 45 minutes, there are two bacteria.
after next 45 minutes ( 90 min) , there are 2² = 4 bacteria
after next 45 minutes (135 min) , there are 2³ = 8 bacteria
after next 45 minutes (180 min), there are 2⁴ = 16 bacteria.
Therefore 16 bacteria could be present at the end of 180 minutes.
