यदि \(U=\{0,1,2,3,4,5,6,7,8,9\}\) और \(A={x:x\in U, x^2<25}\), तो (A') क्या है?
If \(U=\{0,1,2,3,4,5,6,7,8,9\}\) and \(A={x:x\in U, x^2<25}\), what is (A')?
Explanation opens after your attempt
Correct Answer
A. ({5,6,7,8,9})
Concept
In (U), \(x^2<25\) gives (0,1,2,3,4). Therefore the complement is ({5,6,7,8,9}).
Why this answer is correct
The correct answer is A. ({5,6,7,8,9}). In (U), \(x^2<25\) gives (0,1,2,3,4). Therefore the complement is ({5,6,7,8,9}).
Exam Tip
\(x^2<25\) के लिए (U) में (0,1,2,3,4) आते हैं। इसलिए पूरक ({5,6,7,8,9}) है।
