In the expansion of `(1 + x)^(50)` the sum of the coefficients of the odd power of x is

Text Solution

Verified by Experts

The correct Answer is:
`2^(49)`
We have,
`(1+x)^(50) = .^(r=0)overset(5)sum.^(50)C_(r )x^(r )`
Therefore, sum of coefficient of odd powers of x is
`.^(50)C_(1) + .^(50)C_(3) + "……" + .^(50)C_(49) = (1)/(2) (2^(50)) = 2^(49)`
