यदि \(^{8}P_3\) को \(^{8}C_3\) से जोड़ा जाए तो कौन-सा संबंध सही है?

If \(^{8}P_3\) is connected with \(^{8}C_3\) which relation is correct?

Explanation opens after your attempt
Correct Answer

A. \(^{8}P_3=^{8}C_3\times6\)

Step 1

Concept

Because (3!=6) and \(^{n}P_r=^{n}C_r\times r!\). In exams find (r!) quickly.

Step 2

Why this answer is correct

The correct answer is A. \(^{8}P_3=^{8}C_3\times6\). Because (3!=6) and \(^{n}P_r=^{n}C_r\times r!\). In exams find (r!) quickly.

Step 3

Exam Tip

क्योंकि (3!=6) और \(^{n}P_r=^{n}C_r\times r!\) होता है। परीक्षा में (r!) को तुरंत निकालें।
