\\ $=\frac { { b }^{ 4 } }{ { n }^{ 4 } } \left.( \frac { { n }^{ 2 }+2n+1 }{ 4 }  \right.) =\frac { { b }^{ 4 } }{ 4 } \left.( \frac { { n }^{ 2 }+2n+1 }{ 4 }  \right.)  }  }  }

I have a problem with this part of the code, the following error appears

!Missing} inserted. <insterted text>}\\$

    You enter math mode with $: do you ever leave math mode with a closing $? Commented Feb 2, 2016 at 18:44

  • What should \left. and \right. do? They do nothing good and much bad.

  • This seems to be fragment of your code from question tex.stackexchange.com/questions/290784/…, where in my answer I provide complete working code. I also in my comment point where is error and what were other errors ...

\documentclass{standalone}
\usepackage{amsmath}
\begin{document}
$\frac { { b }^{ 4 } }{ { n }^{ 4 } } \left( \frac { { n }^{ 2 }+2n+1 }{ 4 }  \right) =\frac { { b }^{ 4 } }{ 4 } \left( \frac { { n }^{ 2 }+2n+1 }{ 4 }  \right)$
\end{document}

Note that I have written \left and not \left. In your code there were to many curly brackets and $ was missing.
