Consider the expansion of (1 + x)^(2n+1) The sum of the coefficients of all the terms in the expansion is

If the number of terms in the expansion of (1-(2)/(x)+(4)/(x^2))^n, x ne 0 is 28, then the sum of the coefficients of all the terms in this expansion, is

IF the number of terms in the expansion of (1-(2)/(x)+(4)/(x^(2)))^(n),xne0 is 28 ,then the sum of the coefficients of all the terms in this expansion is

If the number of terms in the expansion of (1-2/x+4/(x^(2)))^n x ne 0 , is 28 , then the sum of coefficient of all the terms in this expansion, is
