Answer:

387,420,489

Explanation:

The order of operations tells you that exponential terms must be evaluated first, before multiplication:

(9^-3)(9^12) = (1/729)(282,429,536,481) = 387,420,489

__

The rules of exponents tell you that this can be simplified before it is evaluated.

(9^-3)(9^12) = 9^(-3+12) = 9^9 = 387,420,489
