In the expansion of `(1+x)^(50),`find the sum of coefficients of odd powers of `xdot`A. `2^(26)`B. `2^(49)`C. `2^(50)`D. `2^(51)` |

Answer» Correct Answer - B Sum of odd terms of expansion `(a+b)^(n) "is" (1)/(2).2^(n)`. `therefore` Sum of odd terms of expansion `(1+x)^(50)"is"(1)/(2).2^(50)`. `=2^(-1).2^(50)=2^(49)` |
