How do I do this question ???

A type of malignant tumour cell divides every 8 hours. box
Starting with one of these cells, how many tumour cells will be present after 4 weeks?
Assume none of these cells will die.
Give your answer in standard form.
answer is 1.9/1.93 x 10^25 =
1) find out how many hours are in 4 weeks (4 wks = 28 days, 28x24 =672)

2) next find out how many cell divisions will there be in 672 hours (672/8 = 84)

3) then find out how many cells you will have after 84 divisions (2^84) = 1.93x10^25

I don't get why it isn't 2^83 though
when the singular cell divides into 2, that's one division

Yes and there were 84 of those... 2^1 = 2
