1. Prove that if A is symmetric and B is skew-symmetric, then {A,B} is a linearly independent set.

I am going to need some help to solve this. Not sure how to begin.

Try stating the definition of what linear independence means applied to {A,B}. What happens if you take a transpose?
 
in short the definition leads to the solution only being the trivial solution.

I would hope so. That's what linear independence means, if I'm deciphering your response correctly.
 
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...
