How do you use de Moivre's theorem to find roots
Find the root by De Moivre’s theorem:
De Moivre’s theorem states that:
Suppose is a complex number and be a positive integer such that
For example;
Let a complex number be
Here, and
Now, Apply De Moivre’s theorem to find the roots
Hence, De Moivre’s theorem is used to find the roots of complex numbers.
