Answer

5,600,000

Explanation

In 652 minutes, the bacteria will double 4 times.

163×4=652.

The starting population is 350,000.

After 163 minutes, the bacteria doubles once.

350,000×2 = 700,000

After another 163 minutes, the bacteria doubles again.

700,000×2 = 1,400,000

After another 163 minutes, the bacteria doubles again.

1,400,000×2 = 2,800,000

And finally, when 652 minutes past in total, the bacteria will be at 5,600,000.

2,800,000×2 = 5,600,000

So the population of the bacteria after 652 minutes will be 5,600,000.

Also, if you wanted to write an expression for this, it would be...

350,000×2^4

350,000 is multiplied by 2, 4 times.

Either way, you would get 5,600,000.
