The discussion revolves around the proper formatting of mathematical expressions in LaTeX, specifically focusing on the square root of x. Participants clarify that the expression \({\root{2}\of{x}}\) is indeed the square root of x, but suggest that using \(\sqrt{x}\) is simpler and more straightforward. There is also advice on avoiding unnecessary spaces in LaTeX commands and the importance of previewing posts to ensure correct formatting. Overall, the consensus is that while both methods are valid, \(\sqrt{x}\) is preferable for its simplicity unless dealing with more complex equations.
