यदि \(A={x:x\in \mathbb{N}, x^2-7x+12=0}\) और \(B=\{3,4\}\) हैं तो सही कथन कौन सा है?

If \(A={x:x\in \mathbb{N}, x^2-7x+12=0}\) and \(B=\{3,4\}\) then which statement is correct?

Explanation opens after your attempt
Correct Answer

A. (A=B)

Step 1

Concept

The solutions of the equation are (3) and (4), so the two sets are equal. First solve the equation and then match the elements.

Step 2

Why this answer is correct

The correct answer is A. (A=B). The solutions of the equation are (3) and (4), so the two sets are equal. First solve the equation and then match the elements.

Step 3

Exam Tip

समीकरण के हल (3) और (4) हैं इसलिए दोनों समुच्चय समान हैं। पहले समीकरण हल करें फिर अवयव मिलाएं।
