My "Computational World" class is supposedly an intro to computer science without programming, but the questions are all over the place. I'm completely stuck on this question:(adsbygoogle = window.adsbygoogle || []).push({});

Show expressions for:

(a). 3 cube roots of -1

(b). 4 fourth roots of -1

(c). In the general case, N nth-roots of -1

My professor said that we could use graphs with vectors. He showed us an example of the 3 cube roots of 1, but I have no idea what any of that meant. I unfortunately have no work to show for my attempt because I have no idea what he means. Please help
