यदि ( \frac{(n+6)!}{(n+4)!}+\frac{(n+5)!}{(n+3)!}=338 ), तो (n) का मान क्या है?
If ( \frac{(n+6)!}{(n+4)!}+\frac{(n+5)!}{(n+3)!}=338 ), what is the value of (n)?
Explanation opens after your attempt
A. (8)
Concept
The simplified form is (2(n+5)2). From (2(n+5)2=338), (n+5=13), so (n=8).
Why this answer is correct
The correct answer is A. (8). The simplified form is (2(n+5)2). From (2(n+5)2=338), (n+5=13), so (n=8).
Exam Tip
सरल रूप (2(n+5)2) है। (2(n+5)2=338) से (n+5=13), इसलिए (n=8)।
