Question

A pathologist observes that a culture of cells triples in two days. Suppose the growth of cells is exponential, find the number of cells in 6 days.

Answer 1

in two days it triples
in two more days it triples again
and in two more days it triples one more time
so if the initial population (which you did not write) is \(P\) then in 6 days there will be \(P\times 27\)

Answer 2

So the equation is?
