Looks like unwanted expansion. You can try \string\sqrt and \string\frac in
you example.

If you have a bit recent version of context, you can say:
\starttext
\setupMPpage[offset=1pt]
\startMPpage
label.lft (btex $\displaystyle \frac{a-b}{2}$ etex, (1cm,0)) ;
label.top (btex $\sqrt{ab}$ etex, (3cm,0)) ;
\stopMPpage
\stoptext
and get a stand alone graphic, that can be included in latex. (more on that
in the mtafun manual).
I will send you the pdf off list
