If (a*b=a+b+ab), choose the correct statement about (a*b=b*a).यदि (a*b=a+b+ab) है, तो (a*b=b*a) के बारे में सही कथन चुनिए।
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It is true for all real (a,b)यह हर वास्तविक (a,b) के लिए सत्य है
Step 1: (b*a=b+a+ba). Step 2: Since (b+a=a+b) and (ba=ab), both are equal. Step 3: To prove commutativity, write both forms side by side.चरण 1: (b*a=b+a+ba) होगा। चरण 2: (b+a=a+b) और (ba=ab), इसलिए दोनों बराबर हैं। चरण 3: क्रमविनिमेयता सिद्ध करते समय दोनों रूपों को साथ-साथ लिखें।
