यदि \(A={x:x\in \mathbb{Z}, x^2-4x+3=0}\) और \(B=\{1,3\}\), तो सही संबंध कौन सा है?

If \(A={x:x\in \mathbb{Z}, x^2-4x+3=0}\) and \(B=\{1,3\}\), which relation is correct?

Explanation opens after your attempt
Correct Answer

A. (A=B)

Step 1

Concept

The equation gives ((x-1)(x-3)=0), so \(A=\{1,3\}\). Equal sets have the same elements, order is not important.

Step 2

Why this answer is correct

The correct answer is A. (A=B). The equation gives ((x-1)(x-3)=0), so \(A=\{1,3\}\). Equal sets have the same elements, order is not important.

Step 3

Exam Tip

समीकरण से ((x-1)(x-3)=0), इसलिए \(A=\{1,3\}\)। बराबर समुच्चय में अवयव वही होते हैं, क्रम जरूरी नहीं।
