WebBy Fermat theorem a^phi (m) == a (mod m) => a^ (phi (m) — 1) == 1 (mod m). In this problem m == 10^9 + 7 is prime, so phi (m) == m — 1. So A^ (B^C) (mod m) == A^ (B^C mod (phi (m) — 1)) (mod m) == A^ (B^C mod (m — 2)) (mod m). Yes, I'm applying that theory,but the judge sentence is wrong answer.
