WebbTo determine whether 41 is a square modulo 1000000, we can use the Tonelli-Shanks algorithm, which is an efficient algorithm for finding square roots modulo a prime or prime power. In this case, 1000000 is not a prime, but since it is a power of 10, we can use the Chinese Remainder Theorem to compute square roots modulo its prime factors.
