If the identity element is (0) for (a*b=a+b), what is the inverse of (5)?यदि (a*b=a+b) में तत्समक अवयव (0) है, तो (5) का प्रतिलोम कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-5)(-5)
Step 1: For inverse (x), we need (5*x=0). Step 2: (5+x=0) gives (x=-5). Step 3: In addition, the inverse is the element with the opposite sign.चरण 1: प्रतिलोम (x) के लिए (5*x=0) होना चाहिए। चरण 2: (5+x=0) से (x=-5) मिलता है। चरण 3: जोड़ वाली संक्रिया में प्रतिलोम विपरीत चिह्न वाला अवयव होता है।
