यह ((n+2)(n+1)n(n-1)=5040) है। \(10\cdot9\cdot8\cdot7=5040\), इसलिए (n=8)। / It is ((n+2)(n+1)n(n-1)=5040). Since \(10\cdot9\cdot8\cdot7=5040\), (n=8).
Mathematics Answer, Explanation and Revision Hints
यदि ( \frac{(n+2)!}{(n-2)!}=5040 ), तो (n) का मान क्या है? / If ( \frac{(n+2)!}{(n-2)!}=5040 ), what is the value of (n)?
Correct Answer: B. (8). Explanation: यह ((n+2)(n+1)n(n-1)=5040) है। \(10\cdot9\cdot8\cdot7=5040\), इसलिए (n=8)। / It is ((n+2)(n+1)n(n-1)=5040). Since \(10\cdot9\cdot8\cdot7=5040\), (n=8).
