In this paper we prove three results on semi-prime rings.
If R is a 2-torsion free semi-prime ring satisfying [(xy)2, [xy,yx]] = 0 for all x,y in R, then R is commutative.
If R is a 2-torsion free semi-prime ring satisfying [xyn, [xy,yx]] = 0 for all x, y in R, then R is commutative.
If R is a 2-torsion free semi-prime ring satisfying [ynx, [xy,yx]] = 0 for all x,y in R, then R is commutative.
