of e Coli bacteria multiplied by a factor of ex
00:11
every two milliseconds If there are sixty four bacteria after
00:15
six milliseconds and one bacterium was initially present what is
00:20
x Well e Coli has a bad rap but apparently

00:27
there are quite a few good guys in this gang

to revamp their image If the strain of bacteria multiplies
00:36
every two milliseconds and six milliseconds passed then the bacteria
00:41
has multiplied three times right So that would be x
00:44
cubed In other words we're looking at the cube root
00:47
of sixty For which four times for sixteen times on
00:51
before is sixty four Yeah we're looking at a strain
00:53
that multiplies by four every two milliseconds We're going to 00:00:58.423 --> [endTime] go wash our hands Yeah answer is b
