A certain population of insects starts at 16 and doubles every 6 days. What is the population after 60 days?

The cells of a bacterial double itself every hour. How many cells will there be after 8 hours, if initially we start with 1 cell. Express the answer in powers.

It was observed in an experiment that the number of bacteria doubles evey hour. It was found that the number of bacteria twelve hours from the start of observation was 40960. After how many hours from the start of the experiment would the number of bacteria has been one-fourth the final number of bacteria?

The population of a bacteria culture doubles in number every 12 minutes. The ratio of the number of bacteria at the end of 1 hour to the number of bacteria at the beginning of that hour is
