If (R^{-1}=R), which conclusion is correct for (R)?यदि (R^{-1}=R), तो (R) के लिए कौन-सा निष्कर्ष सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (R) is symmetric(R) सममित है
Step 1: (R^{-1}=R) means every reverse pair is also in the same relation. Step 2: This is exactly the main condition of a symmetric relation. Step 3: When you see equality with the inverse relation, identify symmetry quickly.चरण 1: (R^{-1}=R) का अर्थ है कि हर उलटा युग्म भी उसी संबंध में है। चरण 2: यही सममित संबंध की मुख्य शर्त है। चरण 3: प्रतिलोम बराबरी देखकर तुरंत सममितता पहचानें।
