A bacteria colony doubles in size every hour. At 1:00 pm there are 10 bacteria in a petri dish. At 9:00 pm on the same day, what is the bacteria population?
I need to find out how many times the bacteria population doubled in the 8 hours from 1:00 pm to 9:00 pm. To find the final population, I need to multiply the initial population by 2 raised to the power of 8, because each doubling multiplies the population by 2. So, the final population is 10 times 2^8, which is 10 times 256, which is 2560.
