For the operation (a\ast b=a+b) on real numbers, what is the inverse of (5)?वास्तविक संख्याओं पर क्रिया (a\ast b=a+b) के लिए (5) का प्रतिलोम अवयव क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-5)(-5)
Step 1: The identity element for addition is (0). Step 2: The inverse of (5) is a number (x) such that (5+x=0), so (x=-5). Step 3: For addition, the inverse is the negative of the number.चरण 1: जोड़ में तत्समक अवयव (0) होता है। चरण 2: (5) का प्रतिलोम ऐसा (x) होगा कि (5+x=0)। इसलिए (x=-5)। चरण 3: जोड़ के लिए प्रतिलोम संख्या का ऋणात्मक होता है।
