If a bacterial cell divides every 15 minutes, how many bacteria will be produced in 2 hours?

Explanation

In 2 hours, there are a total of $2 \times 60 = 120$ minutes. There will be $120 \div 15 = 8$ intervals of 15 minutes in 120 minutes, therefore, starting from one bacterial cell, a total of $2^8$ cells, i.e., 256 bacterial cells, will be produced in 2 hours.
