Understanding how to find roots of a complex number is essential for students and professionals working with complex analysis, electrical engineering, and physics. This article provides a clear, step‑by‑step method to extract any nth root of a complex number using its polar representation and De Moivre's theorem Which is the point..
What Is a Complex Number?
A complex number is an expression of the form
[
z = a + bi,
]
where (a) and (b) are real numbers, and (i) is the imaginary unit satisfying (i^{2} = -1). The real part (a) is
