"Webb(7) (a) Use Fermat’s Little Theorem to ﬁnd the last digit of 3100. (b) Let a be any positive integer. Show that a and a5 have the same last digit. Solution: (a) We have that 3 4≡ 1 (mod 5) and 3 ≡ 1 (mod 2); hence 3 ≡ 1 (mod 10). As a result, we have 3100 = (34)25 ≡ 125 ≡ 1 (mod 10), and so the last digit of 3100 is equal to 1.
