( \frac{m!}{(m-2)!(m-1)} ) का सरल रूप क्या है?

What is the simplified form of ( \frac{m!}{(m-2)!(m-1)} )?

Explanation opens after your attempt
Correct Answer

A. (m)

Step 1

Concept

(m!=m(m-1)(m-2)!), so (m) remains after cancellation. Expand the factorial exactly up to the needed limit.

Step 2

Why this answer is correct

The correct answer is A. (m). (m!=m(m-1)(m-2)!), so (m) remains after cancellation. Expand the factorial exactly up to the needed limit.

Step 3

Exam Tip

(m!=m(m-1)(m-2)!), इसलिए काटने पर (m) बचता है। फैक्टोरियल को ठीक उसी सीमा तक फैलाएं।
