What is the symmetric closure of (R={(1,1),(1,2),(2,1),(2,3)})?(R={(1,1),(1,2),(2,1),(2,3)}) का सममित आवरण कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (R\cup{(3,2)})(R\cup{(3,2)})
Step 1: ((1,1)) is self-reverse, and ((1,2),(2,1)) are already paired. Step 2: Only the reverse of ((2,3)), namely ((3,2)), is missing. Step 3: A symmetric closure does not require adding unnecessary diagonal pairs.चरण 1: ((1,1)) अपना उल्टा स्वयं है और ((1,2),(2,1)) पहले से जोड़ी में हैं। चरण 2: केवल ((2,3)) का उल्टा ((3,2)) गायब है। चरण 3: सममित आवरण में अनावश्यक विकर्ण युग्म जोड़ना जरूरी नहीं।
