If (R) is a symmetric relation, what is (R\cup R^{-1}) equal to?यदि (R) सममित संबंध है, तो (R\cup R^{-1}) किसके बराबर होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (R)(R)
Step 1: In a symmetric relation, (R^{-1}=R). Step 2: Therefore, (R\cup R^{-1}=R\cup R=R). Step 3: This idea is useful for both union and intersection questions involving inverses.चरण 1: सममित संबंध में (R^{-1}=R) होता है। चरण 2: इसलिए (R\cup R^{-1}=R\cup R=R)। चरण 3: संघ और प्रतिच्छेद दोनों में यह विचार उपयोगी है।
