Sorry, Chum, it's against the rules of PF to solve things for you. You've got to show some of your own work in order to get help.

Is this for HW?

Thread moved to HH/Calculus.

It looks like the PDF helps to define the problem, but you still need to show some effort on the math questions that you are asking. What approach do you think you should use?
 
Chumlee, here are the instructions you are missing and the template you need to fill out.

Use the template provided

• You must show your attempt at solving the problem
• Write the text of the problem here, not in an attachment or an image.

Thread 'Finding the nth roots of a complex number'

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
