Why is (a*b=a-b) not associative on real numbers?वास्तविक संख्याओं पर (a*b=a-b) साहचर्य क्यों नहीं है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Because ((5*2)*1\ne5*(2*1))क्योंकि ((5*2)*1\ne5*(2*1))
Step 1: ((5*2)*1=(5-2)-1=2). Step 2: (5*(2*1)=5-(2-1)=4). Step 3: They are not equal, so associativity fails.चरण 1: ((5*2)*1=(5-2)-1=2)। चरण 2: (5*(2*1)=5-(2-1)=4)। चरण 3: दोनों बराबर नहीं हैं, इसलिए साहचर्यता नहीं है।
