after 20 min a>2a after 20 min 2a>4a so after4 hours = 4*3 (20min) \[a \times 2^{12}=4096 a\]

"each" microbes means A =1 so u just need 'n' now how many '20 minutes' interval are there in 4 hrs ?

"population of only one microbe" thats why A=1

The difficulty that I have is when it says about A being the initial size of the population. What does that mean?

initial population means how many microbes are taken into consideration before reproduction process starts

Doesn't this have a repetition of like 12 more times then? Or something else?

in 4 hours? since they reproduce every 20 minutes, in 4 hours, they will reproduce 12 times. thats why n=12 now you have everything you need to use the formula given.

Yes I was talking for 4 hours. Anyway, will the formula be like: \[P=12 \times 2^{12}\] @hartnn

Okay. Makes more sense now. This is because the first size was 1 right? But would the new formula be like: \[P= 1 \times 2^{12}\]

yes, correct. initial means only at the beginning, not at every interval ...
