WebbTHE NTH ROOT THEOREM To find the nth root of a complex number in polar form, use the formula given as z1 n = r1 n[cos(θ n + 2kπ n) + isin(θ n + 2kπ n)] where k = 0, 1, 2, 3,..., n − 1. We add 2kπ n to θ n in order to obtain the periodic roots. Example 6.5.2: the Root of a Complex Number Evaluate the cube roots of z = 8(cos(2π 3) + isin(2π 3)). Webb25 apr. 2024 · The nth-root is defined as follows. x 1 n := sup { y ∈ R: y ≥ 0 and y n ≤ x }. Previously, the following lemma has been proven. " Lemma 5.6.5: "Let x ≥ 0 be a non-negative real, and let n ≥ 1 be a positive integer. Then the set E := { y ∈ R: y ≥ 0 and y n ≤ x } is non-empty and is also bounded above. In particular, x 1 n is a real number."
