 Abstract
In this paper we prove that if T is a k-th root of a p­hyponormal operator when T is compact or T is normal for some integer n > k, then T is (generalized) scalar, and that if T is a k-th root of a semi-hyponormal operator and have the property (T) is contained in an angle < 2/k with vertex in the origin, then T is subscalar.
