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
A. (A=B)
Concept
The solutions of \(x^2=16\) are (-4) and (4) so both sets have the same elements. In exams compare elements not order.
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.
Exam Tip
\(x^2=16\) के हल (-4) और (4) हैं इसलिए दोनों में वही अवयव हैं। परीक्षा में क्रम नहीं अवयव देखें।
