Answer:
3'700,000 cfu
Explanation:
One way to count the amount of bacteria in a medium is by doing a dilution of the sample and count how many colonies growth. Each colony is a cfu (Colony forming units).
In the problem, you count 37 colonies. The dilution was 1:100,000. That means the bacteria present in the soap is:
37 colonies × (100,000 / 1) = <em>3'700,000 cfu</em>
