WebFeb 13, 2014 · The cube roots of (, θ) are (3√, θ 3), (3√r, θ + 2π 3) and (3√ θ + 4π 3) (recall that adding 2π to the argument doesn't change the number). In other words, to find the cubic roots of a complex number, take the cubic root of the absolute value (the radius) and divide the argument (the angle) by 3. i is at a right angle from 1: i ... WebOct 6, 2024 · Definition 8.1.16. Given a real number a and a positive integer n, an “ nth root of a” is a number x such that xn = a. For example, 2 is a 6th root of 64 since 26 = 64 and −3 is a fifth root of −243 since ( − 3)5 = − 243. The case of even roots (i.e., when n is even) closely parallels the case of square roots.
