Question

hour expression number of cells 1 2 2 2 2·2 4 3 2·2·2 8 4 2·2·2·2 16 complete the statements. the number of cells increases by a factor of

Explanation:

Step1: Analyze the growth pattern

We have the number of cells at hour 1 is 2, at hour 2 is 4 ($2\times2$), at hour 3 is 8 ($2\times2\times2$), at hour 4 is 16 ($2\times2\times2\times2$).

Step2: Calculate the ratio

To find the factor by which the number of cells increases, we divide the number of cells at a later hour by the number of cells at the previous hour. For example, $\frac{4}{2}=2$, $\frac{8}{4} = 2$, $\frac{16}{8}=2$.

2
