我们姑且先不考虑教科书关于√2不是有理数的证明是否有效，我们先讨论√2不是有理数的反论题到底是什么？是√2=p/q（p和q全是整数），还是√2=p/q（p，q 互质），抑或二者皆可？

Let's not consider whether the textbook's proof that √ 2 is not a rational number is valid. Let's first discuss what is the inverse proposition that √ 2 is not a rational number? Is √ 2 = P / Q (P and Q are all integers), or √ 2 = P / Q (P, Q coprime), or both?

Let's not consider whether the textbook's proof that √2 is not a rational number is valid. Let's first discuss what exactly is the anti-argument that √2 is not a rational number? Is it √ 2 = p/q (both p and q are integers), or √2=p/q(p, q are prime), or both?
