Question

find all the the complex fourth roots of -1-i. you may leave answers in polar form

Answer 1

The question implies changing to polar form
\[ m e^{i \theta} \]
m is the magnitude. for a complex number in cartesian form
a + bi
\[ m= \sqrt{a^2+b^2} \]

the angle (measured counter-clockwise from the positive x-axis) is
