  • Which is your specific problem? The product symbol? – CarLaTeX Mar 07 '22 at 05:38
  • Yes, and how to add the range in that product symbol like r=1, r not equal to i to m – Turing101 Mar 07 '22 at 05:42

    Since you have been a member of this site for two years, you should be able to create a minimal example: https://tex.meta.stackexchange.com/questions/228/ive-just-been-asked-to-write-a-minimal-working-example-mwe-what-is-that. Remember to add it not to have your question downvoted next time. – CarLaTeX Mar 07 '22 at 06:04

The product symbol is reproduced with \prod, with the usual way for the indices (^ and _).

\documentclass{article}

\begin{document}
[
C_i=\left(\prod^{m}_{r=1,r\neq i}\frac{-x_r}{x_i-x_r}\right)f(x_i)\times P
]
\end{document}
