An amoeba reproduces by fission, splitting itself into two separate amoebae. An amoeba reproduces every two days. How many days will it take one amoeba to divide into 16 amoebae?
The amoeba will divide into 1 * 2 = <<1*2=2>>2 amoebae after 2 days.
The amoeba will divide into 2 * 2 = <<2*2=4>>4 amoebae after 4 days.
The amoeba will divide into 4 * 2 = <<4*2=8>>8 amoebae after 6 days.
The amoeba will divide into 8 * 2 = <<8*2=16>>16 amoebae after 8 days.
