यदि \(U={x:x\in \mathbb{Z},-5\le x\le 5}\) और \(A={x:x^2\le 9}\), तो (A') क्या होगा?
If \(U={x:x\in \mathbb{Z},-5\le x\le 5}\) and \(A={x:x^2\le 9}\), what is (A')?
Explanation opens after your attempt
A. \({-5,-4,4,5})
Concept
Here \(A=\{-3,-2,-1,0,1,2,3\}\), so the remaining elements of (U) form (A'). In exams, always find complement inside (U).
Why this answer is correct
The correct answer is A. \({-5,-4,4,5}). Here \(A=\{-3,-2,-1,0,1,2,3\}\), so the remaining elements of (U) form (A'). In exams, always find complement inside (U).
Exam Tip
\(A=\{-3,-2,-1,0,1,2,3\}\) है, इसलिए (U) के बचे अवयव (A') होंगे। परीक्षा में पूरक हमेशा (U) के अंदर ही निकालें।
