I think 1 cell divided 5 times is
2^{5} = ??
Then 5 times that for 5 cells.

^ no, in the exercise it's 4 divisions so it must be 2^4
then multiple to 5

So every time you divide the number before is multiplied by two. So you multiply by two for every example.
5*2*2*2*2
Which would become
5*2^4
=80
