On (A={1,2,3,4}), for (R={(1,2),(2,3),(3,4)}), what is (R\circ R)?समुच्चय (A={1,2,3,4}) पर (R={(1,2),(2,3),(3,4)}) का (R\circ R) कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ({(1,3),(2,4)})({(1,3),(2,4)})
Step 1: ((1,2)) and ((2,3)) give ((1,3)). Step 2: ((2,3)) and ((3,4)) give ((2,4)). Step 3: There is no other two-step chain, so this is (R\circ R).चरण 1: ((1,2)) और ((2,3)) से ((1,3)) मिलता है। चरण 2: ((2,3)) और ((3,4)) से ((2,4)) मिलता है। चरण 3: दो चरणों की और कोई शृंखला नहीं है, इसलिए यही (R\circ R) है।
