How does changing the exponent affect the value?

### Answer

### Answer

Initially, some students may think that the answer is 8^9. This breaks the structure of the problem, as the result has to be 3-digits.

The largest possible 3-digit result is 729 and can be either 3^6 = 729 or 9^3 = 729.

The given answer is incorrect. Although 9^3 = 729, the directions say to use each digit “at most one time each.” This answer repeats the digit 9.
