यदि \(^{13}C_4=^{13}C_m\) और \(m\neq4\) है तो (m) क्या होगा?

If \(^{13}C_4=^{13}C_m\) and \(m\neq4\), what is (m)?

Explanation opens after your attempt
Correct Answer

B. (9)

Step 1

Concept

By symmetry (m=13-4=9). In exams equal combinations may have indices summing to (n).

Step 2

Why this answer is correct

The correct answer is B. (9). By symmetry (m=13-4=9). In exams equal combinations may have indices summing to (n).

Step 3

Exam Tip

Symmetry से (m=13-4=9)। परीक्षा में equal combinations में indices का sum (n) भी हो सकता है।
