यदि \(P={x:x\in \mathbb{N},x<5}\) और \(Q=\{2,4,6\}\) हैं, तो \(P\cup Q\) कौन-सा है?
If \(P={x:x\in \mathbb{N},x<5}\) and \(Q=\{2,4,6\}\), which is \(P\cup Q\)?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,3,4,6} )
Concept
\(P=\{1,2,3,4\}\), so \(P\cup Q={1,2,3,4,6}\). Convert set-builder form to roster form first.
Why this answer is correct
The correct answer is A. ( {1,2,3,4,6} ). \(P=\{1,2,3,4\}\), so \(P\cup Q={1,2,3,4,6}\). Convert set-builder form to roster form first.
Exam Tip
\(P=\{1,2,3,4\}\) है, इसलिए \(P\cup Q={1,2,3,4,6}\) है। पहले set-builder form को roster form में बदलें।
