यदि \(A={x:x\in \mathbb{N},x\le 5}\) और \(B=\{3,4,5,6\}\) है, तो \(A\cup B\) क्या है?
If \(A={x:x\in \mathbb{N},x\le 5}\) and \(B=\{3,4,5,6\}\), what is \(A\cup B\)?
Explanation opens after your attempt
A. ( {1,2,3,4,5,6} )
Concept
Here \(A=\{1,2,3,4,5\}\), so the union is ({1,2,3,4,5,6}). List the natural numbers first.
Why this answer is correct
The correct answer is A. ( {1,2,3,4,5,6} ). Here \(A=\{1,2,3,4,5\}\), so the union is ({1,2,3,4,5,6}). List the natural numbers first.
Exam Tip
यहां \(A=\{1,2,3,4,5\}\) है, इसलिए संघ ({1,2,3,4,5,6}) है। प्राकृतिक संख्याओं को सूचीबद्ध करके हल करें।
