Let Δ(x) denote the error term in the asymptotic formula for the divisor sum. Using a Voronoi-type formula for Δ(x), we prove that ∫ 2 x Δ(x) 3 dx≃cX 4 2 and ∫ 2 x Δ(x) 4 dx≃c'X 2 , where c and c'are some positive constants. The estimate for the third-power moment shows that Δ 3 (x) is strongly biased towards the positive side. We also obtain similar results for E(t), the error term in the mean square formula for the Riemann zeta-function on the critical line, and for P(x), the error term in the circle problem
