Question 1/2 Easy Mathematics Chapter 1: Real Numbers 6: Proof of irrationality of √2, √3, √5 Class 10 Level 18

कौन सा विकल्प \(\sqrt{3}\) के प्रमाण को पूरा करने वाला सही अंतिम वाक्य है?

Which option is the correct final sentence to complete the proof of \(\sqrt{3}\)?

Explanation opens after your attempt
Correct Answer

A. अतः \(\sqrt{3}\) अपरिमेय हैTherefore \(\sqrt{3}\) is irrational

Step 1

Concept

The rational assumption makes both (p) and (q) divisible by (3).

Step 2

Why this answer is correct

This contradicts the coprime condition.

Step 3

Exam Tip

Therefore the final conclusion is that \(\sqrt{3}\) is irrational. चरण 1: परिमेय मान्यता से (p) और (q) दोनों (3) से विभाज्य मिलते हैं। चरण 2: यह सहअभाज्य होने की शर्त से विरोधाभास है। चरण 3: इसलिए अंतिम निष्कर्ष \(\sqrt{3}\) अपरिमेय है।

Correct Answer

A. अतः \(\sqrt{5}\) अपरिमेय हैTherefore \(\sqrt{5}\) is irrational

Step 1

Concept

The rational assumption makes both (a) and (b) divisible by (5).
