Answer 1

Answer:

1/9^3(9^12)

9^12/9^3

9^12-3

9^9

397,420,489

Answer 2

9514 1404 393

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
