26.3. Let d₁, d2,..., dr be the numbers that divide n, including 1 and n. The t-powersigma function ot(n) is equal to the sum of the tth powers of the divisors of n,ot(n) = ₁ + d₂ + ... + dt.For example, 02 (10) = 1² +2²+5² +10² = 130. Of course, σ₁ (n) is just our old friend,the sigma function o(n). (b) Show that if gcd(m, n) = 1, then σt (mn) = 0+ (m)ot (n). In other words, show thatfunction. Is this formula still true if m and n are not relativelyot is a multiplicativeprime?
