समुच्चय \(A={x:x^2=16}\) और \(B=\{-4,4\}\) के बारे में सही कथन कौन सा है?

Which statement is correct about the sets \(A={x:x^2=16}\) and \(B=\{-4,4\}\)?

Explanation opens after your attempt
Correct Answer

A. (A=B)

Step 1

Concept

The solutions of \(x^2=16\) are (-4) and (4) so both sets have the same elements. In exams compare elements not order.

Step 2

Why this answer is correct

The correct answer is A. (A=B). The solutions of \(x^2=16\) are (-4) and (4) so both sets have the same elements. In exams compare elements not order.

Step 3

Exam Tip

\(x^2=16\) के हल (-4) और (4) हैं इसलिए दोनों में वही अवयव हैं। परीक्षा में क्रम नहीं अवयव देखें।
