Question 5: In this question we will discuss the multiplicative properties of the Euler - function. For a given positive integer n let Un = {k € N:1≤k≤n-1, gcd(k, n) = 1}. (a) Compute (n) for n € {3,5,7, 15, 21, 35). Verify that (15) = (3)o(5), (21) = (3)o(7), (35) = (5)o(7). (b) Let m, n be positive integers with ged(m, n) = 1. Use the Chinese remainder theorem to give a bijection between the Cartesian product Um x Un and the set Umn.
