12^n is divisor of 3176793
12 is even number, and 3176793 is odd
thus 12^n should be 1 (and thus n=0)
n^12 - 12^n = -1
12 is even number, and 3176793 is odd
thus 12^n should be 1 (and thus n=0)
n^12 - 12^n = -1

I'm really old, but I'll never be too old to become more educated.

i spent 15 mins for this question because it is not understandable from the question stem that 12.n is explonantial!! so it is NOT 12n but 12^n.
I got the correct version from "cans" reply post...

You are right. I wonder how Cans deciphered 12n as 12^n ?Ozlemg wrote:i spent 15 mins for this question because it is not understandable from the question stem that 12.n is explonantial!! so it is NOT 12n but 12^n.

because there are few who may get it right and there are those who may find it difficult
it is for the latter ... so you can ignore

Posting the question correctly:
If n is a non-negative integer such that 12^n is a divisor of 3,176,793, what is the value of n^12 - 12^n ?

How can 12^n (n=+ve number) be a divisor of ____3, an odd number ? 
I am not sure whether the question makes sense. The only possible value that I see is n=0. but n is non-negative number...

I don't like to sound like a jerk, but this question was typed out in a very confusing way. I assumed 12n = 12*n. I'm not sure people can learn and posters can benefit when questions are not correctly retyped.venmic wrote:This is a good problem to solve try it

"0" is neither positive nor negative integer.voodoo_child wrote:How can 12^n (n=+ve number) be a divisor of ____3, an odd number ? :( I am not sure whether the question makes sense. The only possible value that I see is n=0. but n is non-negative number...
"0" is a non-negative integer.
"0" is also a non-positive integer.
