Question 1/5 Medium Mathematics Chapter 1: Real Numbers 6: Proof of irrationality of √2, √3, √5 Class 10 Level 17

यदि \(\sqrt{3}\) की परिमेय मान्यता गलत सिद्ध हो जाती है, तो सही अंतिम निष्कर्ष क्या है?

If the rational assumption for \(\sqrt{3}\) is proved false, what is the correct final conclusion?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

In contradiction, the opposite assumption is taken.

Step 2

Why this answer is correct

If the rational assumption is proved false, irrationality is proved true.

Step 3

Exam Tip

Therefore the final conclusion is that \(\sqrt{3}\) is irrational. चरण 1: विरोधाभास विधि में उलटी मान्यता ली जाती है। चरण 2: यदि परिमेय मान्यता गलत सिद्ध हो जाए, तो अपरिमेयता सही सिद्ध होती है। चरण 3: इसलिए अंतिम निष्कर्ष \(\sqrt{3}\) अपरिमेय है।

Question 2/5 Medium Mathematics Chapter 1: Real Numbers 6: Proof of irrationality of √2, √3, √5 Class 10 Level 16

कौन सा विकल्प \(\sqrt{3}\) के प्रमाण का सही अंतिम निष्कर्ष और कारण दोनों देता है?

Which option gives both the correct final conclusion and reason in the proof of \(\sqrt{3}\)?

Explanation opens after your attempt
Correct Answer

A. \(\sqrt{3}\) अपरिमेय है क्योंकि परिमेय मानने पर (p) और (q) दोनों (3) से विभाज्य मिलते हैं\(\sqrt{3}\) is irrational because assuming rational makes both (p) and (q) divisible by (3)

Step 1

Concept

Assuming \(\sqrt{3}\) rational gives \(p^2=3q^2\).

Step 2

Why this answer is correct

This proves both (p) and (q) divisible by (3).

Step 3

Exam Tip

This contradicts coprime condition, so \(\sqrt{3}\) is irrational. चरण 1: \(\sqrt{3}\) को परिमेय मानने पर \(p^2=3q^2\) मिलता है। चरण 2: इससे (p) और (q) दोनों (3) से विभाज्य सिद्ध होते हैं। चरण 3: यह सहअभाज्य शर्त से विरोधाभास है, इसलिए \(\sqrt{3}\) अपरिमेय है।

Question 3/5 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।

Question 4/5 Easy Mathematics Chapter 1: Real Numbers 6: Proof of irrationality of √2, √3, √5 Class 10 Level 17

यदि \(\sqrt{3}\) परिमेय मानने से (a) और (b) दोनों (3) से विभाज्य मिलते हैं, तो सही निष्कर्ष क्या है?

If assuming \(\sqrt{3}\) rational makes both (a) and (b) divisible by (3), what is the correct conclusion?

Explanation opens after your attempt
Correct Answer

A. आरंभिक मान्यता गलत हैThe initial assumption is false

Step 1

Concept

At the beginning, (a) and (b) were assumed coprime.

Step 2

Why this answer is correct

Finding both divisible by (3) contradicts this.

Step 3

Exam Tip

Therefore assuming \(\sqrt{3}\) rational is false. चरण 1: शुरुआत में (a) और (b) सहअभाज्य माने गए थे। चरण 2: दोनों (3) से विभाज्य मिलना इस बात के विपरीत है। चरण 3: इसलिए \(\sqrt{3}\) को परिमेय मानना गलत है।

Question 5/5 Easy Mathematics Chapter 1: Real Numbers 6: Proof of irrationality of √2, √3, √5 Class 10 Level 16

\(\sqrt{3}\) के प्रमाण से सही निष्कर्ष कौन सा है?

Which conclusion is correct from the proof of \(\sqrt{3}\)?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

Assuming rationality makes both (p) and (q) divisible by (3).

Step 2

Why this answer is correct

This goes against their being coprime.

Step 3

Exam Tip

Therefore \(\sqrt{3}\) is not rational, but irrational. चरण 1: परिमेय मानने पर (p) और (q) दोनों (3) से विभाज्य मिलते हैं। चरण 2: यह उनके सहअभाज्य होने के विरुद्ध है। चरण 3: इसलिए \(\sqrt{3}\) परिमेय नहीं, बल्कि अपरिमेय है।
