oblemns for Solution: 1. Recall that Euler's phi function (or called Euler's totient function) φ(n) is defined as the number of integers m in the range 1< m<n such that m and n are relatively prime, i.e., gcd(rn, n) l. Find a formula for φ(n), n 2. (Hint: Factor n as the product of prime powers. i.e., n-TiỀ, where pi's are distinct primes and ei 〉 1, i, where p;'s are distinct primes and e > 1 t. oblemns for Solution: 1.
