I know it should work, but is there any particular reason you need to
use #+begin_equation .. #+end_equation ? The following seems to work for
me well.

  #+begin_latex
    \begin{equation}
      \frac{1}{\sqrt{2\pi\sigma^2}}e^{ -\frac{(x-\mu)^2}{2\sigma^2} }
    \end{equation}
  #+end_latex

If you want fontlocking you can even use

  #+begin_src latex :eval yes
    \begin{equation}
      \frac{1}{\sqrt{2\pi\sigma^2}}e^{ -\frac{(x-\mu)^2}{2\sigma^2} }
    \end{equation}
  #+end_src
