WebThe symbol for the cube root is ³√ The cube root of a number is not always an integer. When this is the case use the ³√ button on a calculator and round to 1 decimal place. WebFeb 13, 2014 · The cube roots of (, θ) are (3√r, θ 3), (3√r, θ + 2π 3) and (3√r, 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 ...
