यदि \(U={1,2,\ldots,64}\), \(A={x:x=2^n,\ n\in\mathbb{N},\ 1\le n\le 6}\), तो (|A'|) कितना है?
If \(U={1,2,\ldots,64}\), \(A={x:x=2^n,\ n\in\mathbb{N},\ 1\le n\le 6}\), what is (|A'|)?
Explanation opens after your attempt
Correct Answer
C. (58)
Concept
\(A=\{2,4,8,16,32,64\}\), so (|A|=6). Therefore (|A'|=64-6=58).
Why this answer is correct
The correct answer is C. (58). \(A=\{2,4,8,16,32,64\}\), so (|A|=6). Therefore (|A'|=64-6=58).
Exam Tip
\(A=\{2,4,8,16,32,64\}\), इसलिए (|A|=6)। अतः (|A'|=64-6=58)।
