On (A={1,2,3}), (R={(a,b):|a-b|=0}). What is (R)?(A={1,2,3}) पर (R={(a,b):|a-b|=0}) है। (R) कैसा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Reflexiveपरावर्ती
Step 1: (|a-b|=0) holds exactly when (a=b). Step 2: So ((1,1),(2,2),(3,3)) are all included. Step 3: Equality-based relations are good examples of reflexivity.चरण 1: (|a-b|=0) तभी होता है जब (a=b)। चरण 2: इसलिए ((1,1),(2,2),(3,3)) सभी शामिल होंगे। चरण 3: बराबरी से जुड़ा संबंध परावर्तिता का अच्छा उदाहरण है।
