# Root

 √
Root (√) (%: in J) is a dyadic scalar function that computes the nth root; X√Y is equal to Y*÷X, the right argument raised to the power of the reciprocal of the left argument. The positioning of arguments resembles the mathematical notation ${\displaystyle {\sqrt[{x}]{y}}}$. 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.
