यदि \(U={x:x\in\mathbb{Z},-4\le x\le 4}\) और \(A={x:x^2\le 4}\) है, तो \(A^c\) क्या होगा?
If \(U={x:x\in\mathbb{Z},-4\le x\le 4}\) and \(A={x:x^2\le 4}\), what is \(A^c\)?
Explanation opens after your attempt
A. ({-4,-3,3,4})
Concept
From \(x^2\le 4\), \(A=\{-2,-1,0,1,2\}\). The remaining elements of (U) form \(A^c\).
Why this answer is correct
The correct answer is A. ({-4,-3,3,4}). From \(x^2\le 4\), \(A=\{-2,-1,0,1,2\}\). The remaining elements of (U) form \(A^c\).
Exam Tip
\(x^2\le 4\) से \(A=\{-2,-1,0,1,2\}\) मिलता है। (U) के बाकी तत्व \(A^c\) बनाते हैं।
