In this paper, we study some properties of ( √ SH ), i.e., square roots of semihyponormal operators. In particular we show that an operator T ∈ ( √ SH ) has a scalar extension, i.e., is similar to the restriction to an invariant subspace of a (generalized) scalar operator (in the sense of Colojoarȃ-
