Answer:
387,420,489
Step-by-step 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
