\(^{12}C_9\) को पूरक पहचान से किस रूप में लिखना सरल है?
Using the complementary identity \(^{12}C_9\) is simplest to write in which form?
Explanation opens after your attempt
C. \(^{12}C_3\)
Concept
Choosing (9) is same as leaving (3) so \(^{12}C_9=^{12}C_3\). In exams replace a large index by (n-r).
Why this answer is correct
The correct answer is C. \(^{12}C_3\). Choosing (9) is same as leaving (3) so \(^{12}C_9=^{12}C_3\). In exams replace a large index by (n-r).
Exam Tip
(9) चुनना (3) छोड़ने जैसा है इसलिए \(^{12}C_9=^{12}C_3\) है। परीक्षा में बड़े सूचकांक को (n-r) से बदलें।
