Root

( in J) is a dyadic scalar function that computes the nth root;   is equal to , the right argument raised to the power of the reciprocal of the left argument. The positioning of arguments resembles the mathematical notation $$\sqrt[x]{y}$$. Root shares the glyph  with the monadic function Square Root, which is the same as Root with the default left argument of 2. Root is defined in J, NARS2000, dzaima/APL, and Extended Dyalog APL.
