Hello, John. I opened the slides/slide1.xml in example.pptx to see what is the difference between \sqrt{x} and \sqrt[\square]{x}. There is the diffence:
<m:oMath xmlns:m="http://schemas.openxmlformats.org/officeDocument/2006/math">
<m:rad>
<m:radPr>
<m:degHide m:val="1" />
<m:degHide m:val="on" />
</m:radPr>
<m:deg />
<m:e>
<m:r>
<m:t>x</m:t>
</m:r>
</m:e>
</m:rad>
</m:oMath>
the red one leads "a blank square on the left of root sign"，the blue one leads the correct root sign.
I think the val 1 not = val on in the pptx.
however the xml in sample.docx converted by pandoc is the blue one .

Looks like the pptx writer tries to render math in native
Word format, using texmath to convert just like the docx
writer. I'm not really sure why there would be a difference
in how the same equation appears.
