यदि \(A=\{1,2,3\}\) और \(B=\{2,3,4\}\) है, तो (A\cap \(A\cup B\)) क्या है?
If \(A=\{1,2,3\}\) and \(B=\{2,3,4\}\), what is (A\cap \(A\cup B\))?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,3} )
Concept
\(A\cup B\) contains all elements of (A), so (A\cap \(A\cup B\)=A). This is called the absorption law.
Why this answer is correct
The correct answer is A. ( {1,2,3} ). \(A\cup B\) contains all elements of (A), so (A\cap \(A\cup B\)=A). This is called the absorption law.
Exam Tip
\(A\cup B\) में (A) के सभी अवयव हैं, इसलिए (A\cap \(A\cup B\)=A) है। इसे अवशोषण नियम कहते हैं।
