WebDe Moivre's Theorem to Find Roots of Complex Numbers De Moivre's theorem can also be used to find the nth roots of a complex number as follows If z is a complex number of the form \[ z = r (\cos(\theta)+ i \sin(\theta)) \] then the nth roots are given by \[ z_k = r^{1/n} \left ( \cos \left( \dfrac{\theta + 2k\pi}{n} \right ) + i \sin \left ( \dfrac{\theta + 2k\pi}{n} \right) … Web√5 and √38 are two more examples, as is the cube root of 25, ³√25. But if you multiply the square root of 2 times the square root of 2, you just get 2. And THAT is when we can use this method. ...
