Hi the following is the equation to solve which I am lost as I do not quite understand the method of using complex numbers to solve. Please help!
$ \sqrt[4]{\frac{-18} {1+i\sqrt{3}}} = \frac {\sqrt[4]{18-18i\sqrt{4}}}{4}$
After multiplying the conjugate. But I do not know how to solve the numerator.
Thank You!
I would conjugate the denominator and then use DeMoivre's Theorem with exponent 1/4.
