Synopsis, one of:
\sqrt{arg} \sqrt[root-number]{arg}
The square root, or optionally other roots, of arg. The optional argument root-number gives the root, i.e., enter the cube root of x+y
as \sqrt[3]{x+y}
. The radical grows with the size of arg (as the height of the radical grows, the angle on the leftmost part gets steeper, until for a large enough arg
, it is vertical).
LaTeX has a separate \surd
character (see Math symbols).
