I assume you mean the last digit. The idea is to find a pattern:
8 to the power 1 ends with 8
8 to the power 2 ends with 4
8 to the power 3 ends with 2 (to figure this out, I just multiplied 4 x 8)
8 to the power 4 ends with 6 (once again, multiply the last digit of the previous power x 8)
8 to the power 5 ends with 8
8 to the power 6 ends with 4
...
As you can see, it all repeats, with a period of 4. Therefore, any exponent that is a multiple of 4 will end with 6. Find the nearest multiple of 4 that is smaller than 2015, then continue calculating - always with the last digit.
