Writing a polynomial expression for the square root of k

[mesa]

I need to write, (k)^1/2= a finite term polynomial of 'k' where 'k' is the set of all Reals where 'k' is greater than 0 in math.

Thanks!

You can't write $\sqrt{k}$ as a polynomial in k over $\mathbb{R}$.

You can't write $\sqrt{k}$ as a polynomial in k over $\mathbb{R}$.

That is interesting because you can, but that isn't the question. How do I go from my statement to 'math'.
