For the operation (a\ast b=a-b) on integers, which statement is correct?पूर्णांकों पर (a\ast b=a-b) क्रिया के लिए कौन-सा कथन सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It is not associativeयह साहचर्य नहीं है
Step 1: Use an example to check associativity. Step 2: ((5\ast2)\ast1=(5-2)-1=2), but (5\ast(2\ast1)=5-(2-1)=4). They are not equal. Step 3: Subtraction is generally not associative.चरण 1: साहचर्यता जांचने के लिए उदाहरण लें। चरण 2: ((5\ast2)\ast1=(5-2)-1=2), पर (5\ast(2\ast1)=5-(2-1)=4)। दोनों बराबर नहीं हैं। चरण 3: घटाव सामान्यतः साहचर्य नहीं होता।
