How many cells does a single bacteria cell have after 24 hours?

I actually know the answer to this question. I figured it out yesterday, and it is astounding. I just wanted to know if anyone knows how you say the number because it is super long.

How many cells does a single bacteria cell have after 24 hours?
There was no way to know the answer until you said that the time between divisions is 20 minutes. Once you know that, you can figure out that the bacteria splits 3 times an hour, or 72 times in 24 hours. 2^72 = 4,722,366,482,869,645,213,696, which is different from your answer. Your answer, 4,553,481,496,843,251,613,696, would be said as four sextillion, five hundred fifty three quintillion, four hundred eighty one quadrillion, four hundred ninety six trillion, eight hundred forty three billion, two hundred fifty one million, six hundred thirteen thousand, six hundred ninety six. To say my number, just replace all of the three digit numbers in the name with the appropriate ones from my number; they are the same order of magnitude. You should also note that, as mentioned, a single bacteria cell always has just one cell. The colony would have this many cells, though.
Reply:one, a single cell bacteria will always have just a single cell
Reply:You cannot be so sure about it......

Reply:somewhere in the billions.
Reply:That depends on how long it takes to complete the reproduction process. Different cells have different means of reproducing.
Reply:it actually depends on the doubling time of that bacteria and so on the kind of it!but if doubling time is choosed as 20 minutes (it means that each 20 mins number of bacterias become twice)...after 24 hours we have 2^72 bacteria produced by the single cell!
