Let p and q be distinct primes. Set n = pq and let T, denote the subgroup of the circle group T consisting of the n-th roots of unity. How many primitive nth-roots of unity does T, have? 2kn REMARK: You may use the fact that cis() is a primitive root if and only if gcd(k, n) = 1 without proving it. Let p and q be distinct primes.
