Explanation

22! (22 factorial) = 22 × 21 × 20 × ... × 1 is an extremely large number that far exceeds 22, 32, or 20. Factorials grow faster than exponential functions, so 22! is the maximum possible number that can be formed using exactly two 2's with mathematical notation. 22! is approximately 1.124 × 10^21.
