This draws a square root sign around the contents, for example the square root of 1 + x is expressed as:

    <SQRT>1 + x</SQRT>

and possibly rendered as: (this is the best I can do with ascii art!)

     / 1 + x

The SQRT element has no attributes.

This allows you to specify arbitary roots of an expression. The radix comes first, and is separated from the radicand by the <OF> tag. For example the cube root of 1 + x is expressed as:

    <ROOT>3<OF>1 + x</ROOT>

and possibly rendered as:

    3/ 1 + x

The ROOT element has no attributes.
