 Depends on the field they work in. People dealing with sets,
 rings and fields are very unlikely to come across a square root
 in their day to day work. People who work in cryptography
 though are more likely to deal with more concrete functions,
 including square roots.
 
 n-th roots (which would need to be represented similarly in a
 typographical sense) pop up all over the place when dealing with
 n-dimentional spaces, including the 4-dimentional space-time of
 which Einstein was rather fond, and the cutting-edge string
 theories currently proposed in the world of physics, which
 operate on a universe with up to 11 dimensions.
 
 I think ultimately the best solution, if at all possible, is
 to store the equation in some machine-intelligible format on
 the server and serve it up as an image, as MathML, as HTML or
 as something else depending on client capabilities and
 preferences.
