यदि \(A=\{1,2,3\}\), \(B=\{3,4\}\) और \(C=\{5,6\}\) हैं, तो \(A\times(B-C)\) क्या होगा?
If \(A=\{1,2,3\}\), \(B=\{3,4\}\) and \(C=\{5,6\}\), what is \(A\times(B-C)\)?
Explanation opens after your attempt
A. ({(1,3),(1,4),(2,3),(2,4),(3,3),(3,4)})
Concept
Since (B-C={3,4}), each element of (A) pairs with (3) and (4). Find the difference first and then write the pairs.
Why this answer is correct
The correct answer is A. ({(1,3),(1,4),(2,3),(2,4),(3,3),(3,4)}). Since (B-C={3,4}), each element of (A) pairs with (3) and (4). Find the difference first and then write the pairs.
Exam Tip
क्योंकि (B-C={3,4}), इसलिए (A) के हर अवयव के साथ (3) और (4) जुड़ेंगे। पहले अंतर निकालें फिर युग्म लिखें।
