WebMay 25, 2015 · 3 Answers Sorted by: 3 Tim's answer works, but another way to do it is using De Moivre's theorem. Using this theorem we find that the three complex roots of 27 = 27 ( cos 0 + i sin 0) are given by: z k = 27 3 ( cos 0 + 2 π k 3 + i sin 0 + 2 π k 3) = 3 ( cos 2 π k 3 + i sin 2 π k 3) where k = 0, 1, 2.

Roots of complex numbers - Examples and Explanation

WebNov 4, 2015 · To find a cubic root (or generally root of degree n) you have to use de'Moivre's formula: z1 n = z 1 n ⋅ (cos( ϕ+ 2kπ n) + isin( ϕ + 2kπ n)) for k ∈ {0,1,2,...,n −1} From tis formula you can see, that every complex number has n roots of degree n So to calculate root of a complex number you first have to write the number in a … WebPossible rational roots = (±1±2)/ (±1) = ±1 and ±2. (To find the possible rational roots, you have to take all the factors of the coefficient of the 0th degree term and divide them by all the factors of the coefficient of the highest degree term.) I'll save you the math, -1 is a root and 2 is also a root.
