Abacteria culture is grown with a population of 45 million cells and kept under observation. the cell population is found to double every hour. what will the population be after four hours?

720 million

Step-by-step explanation:

We know that a bacteria culture is grown with a population of 45 million cells and the cell population is doubles every hour.

So to find the population after four hours, we will start by 45 million cells and double the number for every hour till four hours.

Initial population of bacteria culture = 45 million

After one hour = 45 x 2 = 90 million

After two hours = 90 x 2 = 180 million

After three hours = 180 x 2 = 360 million

After four hours = 360 x 2 = 720 million

Therefore, the bacteria population after four hours will be 720 million.
