There is a population of 1,000,000 bacteria in a colony. If the number of bacteria doubles every 230 hours, what will the population be 690 hours from now?

It is 4,000,000 because if it doubles every 230 hours it would be 2,000,000 and if it doubles 690 hours you would just add 2 million more.

After the first 230 hours it doubles,   21 million = 2 million.

After the next 230 hours, that 460 hours later it doubles again = 22 = 4 million.

After the next 230 hours , that is 690 hours later, it doubles again = 2*4 = 8 million.

Population = 8 million.
