We all know that to render a square root in $\mathit{MathJax}$ we just need to write \sqrt{\frac{a}{b}}
which will be rendered as: $$\sqrt{\frac{a}{b}}$$ But I want to make it look prettier just like this (the left one):
WikiPedia has an article about it that you can find
here, but the procedure they suggest doesn't work with $\mathit{MathJax}$.
So does anyone know how to make it look like shown in the left image? Thanks in advance.
