If (a*b=\frac{a+b}{1+ab}), where (1+ab\neq 0), what is the value of (1*2)?यदि (a*b=\frac{a+b}{1+ab}), जहाँ (1+ab\neq 0), तो (1*2) का मान क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (1)(1)
Step 1: (1*2=\frac{1+2}{1+1\cdot 2}). Step 2: This becomes (\frac{3}{3}=1). Step 3: Keep numerator and denominator correct in fraction-based operations.चरण 1: (1*2=\frac{1+2}{1+1\cdot 2})। चरण 2: यह (\frac{3}{3}=1) हो जाता है। चरण 3: हर और अंश दोनों सही रखने से भिन्न वाले प्रश्न आसान हो जाते हैं।
