Correct answer:सही उत्तर: ((1-a)(1-b))((1-a)(1-b))
Step 1: Write (1-a*b=1-(a+b-ab)). Step 2: This becomes (1-a-b+ab=(1-a)(1-b)). Step 3: Such forms connect the operation with ordinary multiplication and simplify proofs.चरण 1: (1-a*b=1-(a+b-ab)) लिखें। चरण 2: यह (1-a-b+ab=(1-a)(1-b)) बनता है। चरण 3: इस प्रकार के रूप संक्रिया को सरल गुणन से जोड़ देते हैं।
