Answer:

1024

Step-by-step explanation:

There are 4 bacteria at the start. We can make an equation to represent the phenomena explained in the question.

As it is written in the question that the bacteria culture doubles in every hour.

So,

Let t represent the unit of time

So the number of bacteria after t unit of time will be  

Number of bacteria after t unit of time=4*2^t

We have to calculate number of bacteria after 8 hours, so t = 8

Number of bacteria after 8 hours=4*2^8

=4*256

=1024

So the bacteria after 8 hours in the culture will be 1024..
