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?
+36916 x * 3 n = 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......
