In general, $\sqrt{a_1 + a_2 + \ldots + a_n} \neq \sqrt{a_1} + \ldots + \sqrt{a_n}$ amongst other things.

Dec11 reviewed Reviewed Application of the mean value theorem to $f(x)=x^{-s}$ (Prop 2.5 in Princeton Lectures in Analysis-Complex Analysis) Dec11 comment Application of the mean value theorem to $f(x)=x^{-s}$ (Prop 2.5 in Princeton Lectures in Analysis-Complex Analysis) You have to take absolute values on both sides after the last step that you wrote. Also, for what value of $c \in [ n, n + 1 ]$ is the right side the largest? That will be an upper bound for the left side.
