Correct Answer

A. \(p^2=3q^2\) से सीधे (p=3q) लिखनाDirectly writing (p=3q) from \(p^2=3q^2\)

Step 1

Concept

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

Step 2

Why this answer is correct

This means (p) is divisible by (3), but (p=3q) does not follow directly.

Step 3

Exam Tip

The correct way is to write (p=3k). चरण 1: \(p^2=3q^2\) से \(p^2\) (3) से विभाज्य मिलता है। चरण 2: इससे (p) (3) से विभाज्य है, पर सीधे (p=3q) नहीं मिलता। चरण 3: सही तरीका (p=3k) लिखना है।
