Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((3,1))((3,1))
Step 1: In (A\times B), the first component must come from (A). Step 2: In ((3,1)), the first component is (3), which is not in (A). Step 3: Position matters a lot in ordered pairs.चरण 1: (A\times B) में पहला घटक (A) से होना चाहिए। चरण 2: ((3,1)) में पहला घटक (3) है जो (A) में नहीं है। चरण 3: क्रमित युग्म में स्थान बहुत महत्वपूर्ण होता है।
