You start with pushing the calculator button in the scroll bar, the one between the flag icon and the x squared icon.

That gives you the tags to invoke Latex.

To get a square root, you type between the tags \sqrt{121} = 11. That results in

$$\displaystyle \sqrt{121} = 11.$$

To get a higher root, you type between the tags \sqrt[5]{32} = 2. That results in

$$\displaystyle \sqrt[5]{32} = 2.$$

The simplest way to learn Latex is to use the reply button on posts that contain LaTeX and look at the code.

\sqrt{2} is the code for the symbolic square root two $$\displaystyle \sqrt2$$
\sqrt[5]{21} is the code for the symbolic fifth root twenty one $$\displaystyle \sqrt[5]{21}$$

My personal favorite is Codecogs. The LaTeX is very similar to the version used here. I don't know the site you refered to, but one of the nice things about Codecogs is that you can save the code as an image and post the image here.

Thanks for posting the link. I'm surprised that \sqrt{} and \sqrt[]{} are not predefined in the TeX package (or, perhaps, their omission from the wiki list was an oversight). I've added your link to the LaTeX notice, along with Dan's.
