What is ( \frac{(n+3)!}{(n+1)!} ) equal to?

Explanation opens after your attempt
Correct Answer

B. ( (n+3)(n+2) )

Step 1

Concept

((n+3)!=(n+3)(n+2)(n+1)!), so the answer is ((n+3)(n+2)). Expand the larger factorial up to the smaller one.

Step 2

Why this answer is correct

The correct answer is B. ( (n+3)(n+2) ). ((n+3)!=(n+3)(n+2)(n+1)!), so the answer is ((n+3)(n+2)). Expand the larger factorial up to the smaller one.

Step 3

Exam Tip

((n+3)!=(n+3)(n+2)(n+1)!), इसलिए उत्तर ((n+3)(n+2)) है। बड़ी फैक्टोरियल को छोटी फैक्टोरियल तक फैलाएं।
