Problem
Solution
We can use an elementary exponents rule to solve our problem.
We know that 
. Hence,

Solution 2
We see that 
Only answer choice 
satisfies this requirement.

Solution 3
Say you somehow forgot the basic rules of exponents, you could just deduce 
is a line of 2000 2000's being multiplied, and if we multiplied by this line by an additional 2000, we would then have 2000's lined up multiplying each other.
