If the identity element is (1) for (a*b=ab), what is the inverse of (4)?यदि (a*b=ab) में तत्समक अवयव (1) है, तो (4) का प्रतिलोम कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\frac{1}{4})(\frac{1}{4})
Step 1: For inverse (x), we need (4x=1). Step 2: Hence (x=\frac{1}{4}). Step 3: In multiplication, think of the reciprocal as the inverse.चरण 1: प्रतिलोम (x) के लिए (4x=1) होना चाहिए। चरण 2: इसलिए (x=\frac{1}{4}) है। चरण 3: गुणन में प्रतिलोम लेते समय संख्या का व्युत्क्रम सोचें।
