Hi, I want to define Re operator by \declaremathoperator command in latex but the operator isn't typeset in Roman.please help me

[Stefan Kottwitz]

Welcome to the forum!

\Re is already defined. You can undefine it and then declare it again as math operator:

\documentclass{article}
\usepackage{amsmath}
\let\Re\relax
\DeclareMathOperator{\Re}{Re}
\begin{document}
This is $\Re(x)$.
\end{document}
