intersection between x-2y+3z=11 and <1,0,-2> + t<3,-1,2>

You know how to check that this really is a solution, right?
 
It fits according to what I know, but I feel like something is wrong.

Mark44 is suggesting you actually check it. Put those numbers into the equation for the plane. Does it work? Check again that it is on the line. Then you won't have to feel like something is wrong.
 
Show us how you did your check. If there's something wrong, I'm sure we'll spot it.
 
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...
