Question

you have a tube containing 10^2 bacteria if you remove 10^2 bacteria how many bacteria are left?

Answer 1

After removing10² bacteria we will have approximately 10to the power 9 bacteria

Answer 2

There will be no bacteria left.

Given that,

Total quantity of bacteria in a tube = 10^2

Number of removed bacteria = 10^2

So, to calculate the number of bacteria that are left, we have to subtract the number of removed bacteria from the total number or quantity of bacteria that are present.

So,

10^2 - 10^2

= 0

Hence, there will be no bacteria left because the total number of bacteria is equal to the number of the bacteria removed.
