摘要：

In this article, we give several inequalities involving powers numerical radii and the usual operator norms of Hilbert space operators. In particular, if A(i), B-i and X-i are bounded linear operators (i = 1,2, ... , n is an element of N), then we estimate the norm as well as the numerical radius to Sigma(n)(i=1) X(i)A(i)(m)B(i) for some m is an element of N.
