    well if it becomes double very 4 hours then it will become 4times in 8 hours and finally 8times after 12 hours so 2^(n/4)* 2000 will be strength of bacteria after n hours clear??

    \[2^{\frac{ 12 }{4 }}\times2000\]

    look it`s getting double of the previous so everytime it`s getting multiplied by 2 say initially they were 2000 in number the they would be 2* 2000 then again next would be 2* 2* 2000 so this can be generalized as 2^m *2000 but observing we find that they multiply every 4 hours not 1 hour so 2^(n/4) * 2000 hope this clears up doubts in your mind
