Translating equation to latex code

\[w\textsubscript{\lambda,\rho}(x\textsubscript{i}) = \dfrac{\lambda \left| \kappa x\textsubscript{i}\right| \textsuperscript{\rho}} {\sum_{k=1}^{\left|V\right|} \left|\kappa x\textsubscript{k}\right|\textsuperscript{\rho} v(x\textsubscript{k})} + \dfrac{(1 - \lambda) \left|\eta(x\textsubscript{i})\right| $\rho$}{\sum_{k=1}^{\left|V\right|}\left|\eta (x\textsubscript{k})\right|\textsuperscript{$\rho$} ν(x\textsubscript{k})}\]

I am trying to write this equation in overleaf but the code doesn't work. What is wrong ? How can i fix it ?
