On (A={1,2,3}), (R={(a,b):(a-b)^2=0}). How should (R) be identified?(A={1,2,3}) पर (R={(a,b):(a-b)^2=0}) है। (R) को कैसे पहचानेंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It is reflexiveयह स्वतुल्य है
Step 1: ((a-b)^2=0) happens only when (a=b). Step 2: So ((1,1),(2,2),(3,3)) are all included. Step 3: The identity relation is reflexive.चरण 1: ((a-b)^2=0) तभी होता है जब (a=b)। चरण 2: इसलिए ((1,1),(2,2),(3,3)) सभी मिलते हैं। चरण 3: पहचान सम्बन्ध भी स्वतुल्य होता है।
