Re: Piccola modifica del comando \sqrt

In ordinary LATEX the placement of root indices is sometimes not so good:
`
\sqrt[\beta]{k}`

In the amsmath package \leftroot and \uproot allow
you to adjust the position of the root:

`\sqrt[\leftroot{-2}\uproot{2}\beta]{k}`

will move the beta up and to the right. The negative argument used with
\leftroot moves the to the right. The units are a small amount that is a
useful size for such adjustments.
