यदि \(U={x:x\in\mathbb{Z},-5\le x\le 5}\) और \(A={x:x^2<9}\) है, तो \(A^c\) क्या होगा?
If \(U={x:x\in\mathbb{Z},-5\le x\le 5}\) and \(A={x:x^2<9}\), what is \(A^c\)?
Explanation opens after your attempt
A. ({-5,-4,-3,3,4,5})
Concept
From \(x^2<9\), \(A=\{-2,-1,0,1,2\}\). Removing these from (U) gives the complement.
Why this answer is correct
The correct answer is A. ({-5,-4,-3,3,4,5}). From \(x^2<9\), \(A=\{-2,-1,0,1,2\}\). Removing these from (U) gives the complement.
Exam Tip
\(x^2<9\) से \(A=\{-2,-1,0,1,2\}\) मिलता है। (U) से इन्हें हटाने पर पूरक मिलता है।
