radical sign n. Mathematics the sign √ used to denote a root of the number or quantity to which it is prefixed.Used by itself, √ indicates the square root; for the cube, fourth, etc., roots, appropriate numbers are added to give the signs ³√, ⁴√, etc.For the history of the sign, see F. Cajori Hist. Math. Notations (1928) II. 366ff. The sign appears in a form similar to the modern one in Christoff Rudolff Behend unnd hubsch Rechnung durch die kunstreichen regeln Algebre, so gemeincklich die Coss genennt werden (1525), and in an English context in R.
