If is an univariate polynomial with degree n then Bombieri norm of P is defined by where denotes the binomial coefficient.In the present paper we give, under assumptions on the roots of P, optimal Bernsteintype inequalities for the ratio between Bombieri norm of P and that of its derivative P′.We also give such inequalities for the polar derivatives of P defined by
