Abstract
Let \(k\geqslant 2\) be a fixed natural number and \(d_k(n)\) denote the number of ways n can be written as a product of k positive integers. We use \(\Delta _k(x)\) to denote the error term in the asymptotic formula of the summatory function of \(d_k(n).\) The aim of this paper is to study the hybrid moments of \(\Delta _2(x)\) and \(\Delta _3(x)\). The higher power moments of \(\Delta _2(x)\) are also studied.
