The number of a certain type of bacteria, y, in a culture is determined by the equation y= 200(4)^x where x is the number of days the culture has been growing. Find the number of bacteria present after 6 days

y = 200(4)^x

x = 6 (after 6 days)

y = 200(4)^6

y = 200(4096)

y = 819,200

After 6 days, there are approximately 819,200 bacteria present in the culture.

To find the number of bacteria present after 6 days, we substitute x = 6 into the equation y = 200(4)^x:

y = 200(4)^6

Now we calculate:

y = 200(4096)

y = 819,200

Therefore, the number of bacteria present after 6 days is 819,200.
