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

यदि (p) (3) से विभाज्य है, तो (p) को किस रूप में लिखना सही है?

If (p) is divisible by (3), what is the correct form of (p)?

Explanation opens after your attempt
Correct Answer

B. (p=3k)

Step 1

Concept

A number divisible by (3) has (3) as a factor.

Step 2

Why this answer is correct

So it is written as (p=3k), where (k) is an integer.

Step 3

Exam Tip

In proofs, write this type of form after getting divisibility. चरण 1: (3) से विभाज्य संख्या में (3) गुणनखंड होता है। चरण 2: इसलिए उसे (p=3k) लिखा जाता है, जहां (k) पूर्णांक है। चरण 3: प्रमाण में विभाज्यता मिलने पर इसी तरह का रूप लिखें।

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

यदि (p) और (q) दोनों (3) से विभाज्य हों, तो सहअभाज्य शर्त से क्या टकराव होता है?

If (p) and (q) are both divisible by (3), what conflict occurs with the coprime condition?

Explanation opens after your attempt
Correct Answer

A. दोनों में (3) साझा गुणनखंड होगाBoth will have (3) as a common factor

Step 1

Concept

Being divisible by (3) means both have (3) as a factor.

Step 2

Why this answer is correct

Coprime numbers should not have a common factor other than (1).

Step 3

Exam Tip

Therefore it gives a contradiction in the proof of \(\sqrt{3}\). चरण 1: (3) से विभाज्य होने का अर्थ है कि दोनों में (3) गुणनखंड है। चरण 2: सहअभाज्य संख्याओं में (1) के अलावा साझा गुणनखंड नहीं होना चाहिए। चरण 3: इसलिए यह \(\sqrt{3}\) के प्रमाण में विरोधाभास देता है।
