यदि \(\sqrt{2}=\frac{p}{q}\) में (p,q) सहअभाज्य हैं, तो (p) और (q) दोनों सम निकलना किस बात का संकेत है?

If (p,q) are coprime in \(\sqrt{2}=\frac{p}{q}\), what does it indicate when both (p) and (q) turn out even?

Correct Answer

A. मान्यता में विरोधाभास हैThere is a contradiction in the assumption

Step 1

Concept

Coprime numbers cannot both be even.

Step 2

Why this answer is correct

Both being even means (2) is a common factor.

Step 3

Exam Tip

Hence the rational assumption is proved false. चरण 1: सहअभाज्य संख्याएँ दोनों सम नहीं हो सकतीं। चरण 2: दोनों सम होने का मतलब है कि (2) साझा गुणनखंड है। चरण 3: इसलिए परिमेय मान्यता गलत सिद्ध होती है।
