यदि \(U={x:x\) (10) से छोटी धनात्मक पूर्ण संख्या है(}) और \(A={x:x^2<20}\), तो (A') क्या है?
If \(U={x:x\) is a positive integer less than (10)(}) and \(A={x:x^2<20}\), what is (A')?
Explanation opens after your attempt
A. ({5,6,7,8,9})
Simple Explanation
\(U={1,\ldots,9}\) और \(x^2<20\) के लिए \(A=\{1,2,3,4\}\) है। बाकी ({5,6,7,8,9}) पूरक है। / \(U={1,\ldots,9}\), and \(x^2<20\) gives \(A=\{1,2,3,4\}\). The remaining set ({5,6,7,8,9}) is the complement.
