Answer:
387,420,489 is the answer to the monomial.
Explanation:
3x^2y = 3(1)^2(9) when the variables are replaced.
3(1) = 3
2(9) = 18
3^18 = 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 = 387,420,489
Therefore, 387,420,489 is the answer to the monomial.
