Why is (a*b=a^2+b^2) commutative on real numbers?वास्तविक संख्याओं पर (a*b=a^2+b^2) क्रमविनिमेय क्यों है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Because (a^2+b^2=b^2+a^2)क्योंकि (a^2+b^2=b^2+a^2)
Step 1: After changing the order, (b*a=b^2+a^2). Step 2: Addition is commutative, so (a^2+b^2=b^2+a^2). Step 3: Commutativity is easy to identify in addition-based forms.चरण 1: क्रम बदलने पर (b*a=b^2+a^2) होगा। चरण 2: जोड़ क्रमविनिमेय है, इसलिए (a^2+b^2=b^2+a^2)। चरण 3: जोड़ वाले रूप में क्रमविनिमेयता आसानी से पहचानी जाती है।
