Hard Mathematics Chapter 1: Real Numbers Class 10 Level 17

\(\sqrt{3}\) को परिमेय मानकर \(\sqrt{3}=\frac{p}{q}\) लिखा गया। \(p^2=3q^2\) से (p) के बारे में सही तर्क कौन सा है?

Assume \(\sqrt{3}\) is rational and write \(\sqrt{3}=\frac{p}{q}\). What is the correct reasoning about (p) from \(p^2=3q^2\)?

Explanation opens after your attempt
Correct Answer

B. (p) (3) से विभाज्य है(p) is divisible by (3)

Step 1

Concept

From \(p^2=3q^2\), \(p^2\) is divisible by (3).

Step 2

Why this answer is correct

Since (3) is prime, (p) is also divisible by (3).

Step 3

Exam Tip

Use the prime rule to move from square to original number. चरण 1: \(p^2=3q^2\) से \(p^2\) (3) से विभाज्य है। चरण 2: (3) अभाज्य है, इसलिए (p) भी (3) से विभाज्य होगा। चरण 3: वर्ग से मूल संख्या पर जाने के लिए अभाज्य नियम लगाएं।
