Question

the cell of a bacteria double itself every hour. how many cells will there be after 8 hours, if initially we start with 1 cell. express the answer in powers ​

Answer 1

Step-by-step explanation:

A scientist begins with a single cell.

The cell of a bacteria double in every 1 hour.

So, the bacteria cell in every 1 hour =1×2=2

So, for every 1 hour passed we have to multiply 2 in previous amount.

So, 8 hours comprises of 8 sets of 1 hour.

So, to get amount of bacteria cell after 8 hours we have to multiply initial cell by 2, 8 times that is we have to multiply it by 2

8

cell of bacterium in 8 h=2

8

×1=2

8

Answer 2

Answer:

256 cell

Step-by-step explanation:

1st hour

1 will double itself

1*2=2

After 2 hour

both 2 cell will double itself

2*2=4

After 3 hour

all 4 will double

4*2=8

Like this

After 4 hour

8*2=16

After 5 hour

16*2=32

After 6 hour

32*2=64

After 7 hour

64*2=128

After 8 hour

128*2=256

Therefore , after 8 hours the number of cell will be 256 .
