If (a*b=a+b-ab), which statement about (0) is correct?यदि (a*b=a+b-ab) है, तो (0) के बारे में सही कथन कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (0) is the identity element(0) तत्समक अवयव है
Step 1: (a*0=a+0-a\cdot 0=a). Step 2: (0*a=0+a-0\cdot a=a) also holds. Step 3: The identity element leaves every element unchanged from both sides.चरण 1: (a*0=a+0-a\cdot 0=a)। चरण 2: (0*a=0+a-0\cdot a=a) भी सही है। चरण 3: तत्समक अवयव दोनों ओर से अवयव को नहीं बदलता।
