I have updated pandoc to version 3.1.8, and there is still a square to the 
right of the root symbol.In slides.xml, the value of m:val="1".If I change 
"1" to "on",the display becomes correct.
I tested the online texmath(texmath demo (johnmacfarlane.net) 
<https://johnmacfarlane.net/texmath.html>), the $\sqrt{x}$ is converted to 
m:val="1"，which causes display errors(a square to the right of the root 
symbol) in PowerPoint.
                                   m:val="1"                  m:val="on"
PowerPoint               Wrong                         Correct
Word                          Correct                        Correct
