Euler's Tution function: (n) is the number of positive integers less than n that are relatively prime to n. Proposition: Proposition: (p) = p - 1 for any prime number p. (p) = pk-pk-1 for any positive integer k and a prime number p. Proposition: (nm) = y(n)y(m) for any two relatively prime n and m (gcd(n, m) = 1). Compute (127). Justify your answer. Compute (625). Justify your answer.
