Determine how many times cells type b divide in a 24 hour period. I f you begin with one type b cell, how many cells will be produced in 24 hours?

(type b cell divides once every six hours)

I need help figuring this one out.

I had a problem before this one that was the same and it's answer was 2 to the 8th power.

(type a cell divided once every 3 hours)

I can't figure out how they got 2 to the 8th power.

Please help
