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):

enter image description here

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.

  • $\begingroup$ On my screen (Chrome with 125% magnification), the horizontal line of the square root is detached from the left "v" part. $\endgroup$ – Frenzy Li Dec 22 '13 at 10:59
  • $\begingroup$ This two versions of root were also compared on TeX.SE: “Closed” (square) root symbol $\endgroup$ – Martin Sleziak Dec 22 '13 at 15:59

Even if this can be achieved with MathJax, please leave complex TeX hacks fine-tuning typography (like ones you're linking to) for your papers — let's keep sources on Math.SE clear and simple.
