$2000^{2001}$

$4000^{2000}$

$2000^{4000}$

$4{,}000{,}000^{2000}$

$2000^{4{,}000{,}000}$

Answer: A

Concepts:exponent

Difficulty rating: 950

Solution:

Writing $2000 = 2000^1,$ we get $\begin{gathered} 2000^1 \cdot 2000^{2000} \\ = 2000^{1 + 2000} \\ = 2000^{2001}. \end{gathered}$

All of the other options are larger than this.

Thus, the correct answer is A.
