यदि ( \frac{(n+6)!}{(n+2)!}-\frac{(n+5)!}{(n+1)!}=2880 ), तो (n) का मान क्या है?

If ( \frac{(n+6)!}{(n+2)!}-\frac{(n+5)!}{(n+1)!}=2880 ), what is the value of (n)?

Explanation opens after your attempt
Correct Answer

B. (5)

Step 1

Concept

The simplified form is (4(n+5)(n+4)(n+3)). Since \(4\cdot10\cdot9\cdot8=2880\), (n=5).

Step 2

Why this answer is correct

The correct answer is B. (5). The simplified form is (4(n+5)(n+4)(n+3)). Since \(4\cdot10\cdot9\cdot8=2880\), (n=5).

Step 3

Exam Tip

सरल रूप (4(n+5)(n+4)(n+3)) है। \(4\cdot10\cdot9\cdot8=2880\), इसलिए (n=5)।
