    Please, don't post images, but codes. Also, inside \[ \] you don't need equation*.

The environment equation (or equation*) triggers math mode. You are already in math display using \[ ... \], which raises an error.

Remove \[ before \begin{equation*} and \] after \end{equation*}. For instance:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{equation*}
\begin{pmatrix}
a&b\\
c&d
\end{pmatrix}
\end{equation*}

\end{document}
