The bacteria in a jar triple every 20 seconds. After three minutes, there are 275,562 bacteria in the jar. How many were in the jar at the beginning of the experiment?

x * 3 = 275 562       n is the number of 20 second periods in three minutes = 9

 

3^9 x  = 275 562

x = 14 of them little critters to start with......
