The thing to notice here is
17^12 is smaller than 1973^9

split it like this 1973's square root is between 40-50 for sure(appr. 45) so,
1973^9 = (45)^18

Now compare 17^12 and (45)^18
clearly second one is bigger so,
-3+1 = 2 is the unit's digit

I think this is a poor-quality question and I don't agree with the explanation. we can calculate as 11-03 that gives 8 as remainder, how can you say 2 as remainder
