Discussion Overview

The discussion revolves around the possibility of expressing the square root of 'k', specifically (k)^(1/2), as a finite polynomial in 'k', where 'k' is defined as the set of all real numbers greater than 0. The scope includes mathematical reasoning and conceptual clarification.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant requests assistance in writing (k)^(1/2) as a finite polynomial of 'k'.
  • Several participants assert that it is not possible to express \sqrt{k} as a polynomial in k over the real numbers.
  • Another participant acknowledges the assertion but indicates a desire to clarify their original statement and its transition to mathematical language.
  • A final response reiterates the claim that \sqrt{k} cannot be expressed as a polynomial in k over \mathbb{R}.

Areas of Agreement / Disagreement

Participants generally agree that \sqrt{k} cannot be expressed as a polynomial in k over the real numbers, but there is a lack of consensus on the implications or the nature of the original request.

Contextual Notes

The discussion does not resolve the underlying assumptions about the definitions of polynomials or the nature of the square root function in this context.

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 [itex]\sqrt{k}[/itex] as a polynomial in k over [itex]\mathbb{R}[/itex].

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