Howdy,
Are you sure \boldsymbol{$5$} compiles? I believe the \boldsymbol needs to be in math mode so $\boldsymbol{5}$ and $\boldsymbol{\xrightarrow{5}}$ work fine.
As a side note you should get used to \(...\) instead of $...$ for inline math (and \[...\] instead of $$...$$ if you use that for display math).
Good Luck,
