(\frac{(n+4)!}{(n+1)!}) में कितने लगातार गुणनखंड बचते हैं?

How many consecutive factors remain in (\frac{(n+4)!}{(n+1)!})?

Explanation opens after your attempt
Correct Answer

B. (3)

Step 1

Concept

(\frac{(n+4)!}{(n+1)!}=(n+4)(n+3)(n+2)), so three factors remain. Reduce the numerator up to the denominator factorial.

Step 2

Why this answer is correct

The correct answer is B. (3). (\frac{(n+4)!}{(n+1)!}=(n+4)(n+3)(n+2)), so three factors remain. Reduce the numerator up to the denominator factorial.

Step 3

Exam Tip

(\frac{(n+4)!}{(n+1)!}=(n+4)(n+3)(n+2)), इसलिए तीन गुणनखंड बचते हैं। हर के फैक्टोरियल तक अंश को घटाएं।
