Mathematics Answer, Explanation and Revision Hints
पूर्णांकों पर (a*b=a+b+1) दिया है। क्या यह संक्रिया सहचारी है? / On integers, (a*b=a+b+1). Is this operation associative?
Correct Answer: A. हाँ / Yes. Explanation: चरण 1: ((a*b)*c) निकालें। यह ((a+b+1)+c+1=a+b+c+2) है। चरण 2: (a*(b*c)=a+(b+c+1)+1=a+b+c+2) है। चरण 3: दोनों बराबर मिलें तो संक्रिया सहचारी होती है। / Step 1: Find ((a*b)*c), which is ((a+b+1)+c+1=a+b+c+2). Step 2: Find (a*(b*c)=a+(b+c+1)+1=a+b+c+2). Step 3: Since both are equal, the operation is associative.
