Add the like terms. You have two whole numbers, 2 and 3, which makes 5. You also have 6i and i, but they're both being subtracted, which make 5-7i (6i=i+i+i+i+i+i, plus i is 7)

The number of viruses was 4000 times greater than number of protozoa.

Step-by-step explanation:

Given,

Number of protozoa = $5*10^5$

Number of viruses = $2*10^9$

Let,

x be the number of times number of viruses is greater than number of protozoa.

Number of viruses = Number of time * Number of protozoa

$2*10^9=(5*10^5)x$

Dividing both sides by $5*10^5$

$\frac{2*10^9}{5*10^5}=\frac{(5*10^5)x}{5*10^5}\\\\4*10^3= x\\x=4*10^3 \\x=4000$

The number of viruses was 4000 times greater than number of protozoa.
