((1+1)^n) रखने से कौन-सी combination पहचान मिलती है?
Which combination identity is obtained by putting ((1+1)^n)?
Explanation opens after your attempt
Correct Answer
A. \(^{n}C_0+^{n}C_1+\cdots+^{n}C_n=2^n\)
Concept
In binomial expansion the sum of all coefficients becomes \(2^n\). In exams use the same identity for total subsets.
Why this answer is correct
The correct answer is A. \(^{n}C_0+^{n}C_1+\cdots+^{n}C_n=2^n\). In binomial expansion the sum of all coefficients becomes \(2^n\). In exams use the same identity for total subsets.
Exam Tip
द्विपद विस्तार में सभी coefficients का योग \(2^n\) हो जाता है। परीक्षा में total subsets के लिए भी यही पहचान उपयोग करें।
