the question is wrong because n is a non-negative integer, 3,176,793 is an odd integer/number and 12^n is an even integer. no matter the value of n, 12^n can not be a divisor of 3,176,793.

First of all, Question is Right

n^12-12^n = -1

only number that satisfies this is n = 0 (which is non-negative integer)

12^0 = 1 which divides the large number

interesting and make sense.

if you include the answer choices, would be much easier.
