I'm lost and don't even know where to start.

Let F = Z mod 2, show F[x]/<x^3+X+1> and F[x]/<x^3+X^2+1> are isomorphic.

I guess fist I need help understanding what those two factor rings look like and what elements they contain.
Thanks

The easiest way would be to notice that both are 8-element fields.
 
I tried but I couldn't find them, what are the eight?
 
Which ones did you find?
 

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...
