On (\mathbb{R}), (a*b=a^2+b^2) is defined. Which property does this operation satisfy?

Answer and explanation

Correct answer: Commutative

Step 1: For commutativity, check whether (a*b=b*a). Step 2: Since (a^2+b^2=b^2+a^2), the operation is commutative. Step 3: Associativity is a different test; swapping (a) and (b) checks commutativity only.
