Any nth root is an exponentiation by 1/n, so to get the square root of 9, you use 9**(1/2) (or 9**0.5) to get the cube root, you use 9 ** (1/3) (which we can't write with a simpler fraction), and to get the nth root, 9 ** (1/n). nth root In mathematics, the nth root of a number x is a number r which, when raised to the power of n, equals x where n is the degree of the root. The nth root (or "nth radical") of a quantity z is a value r such that z=r^n, and therefore is the inverse function to the taking of a power. it is the "radical" symbol (used for square roots) with a little n to mean nth root. 1968, p. 476), though some are possibly degenerate.
