Sum of all binomial cofficients of `( 1 + x )^(2n)`

The sum of the binomial coefficients of [2x+(1)/(x)]^(n) is equal to 256. The constant term in the expansion is: (A) 1120(B)2110(C)1210(D) none

Sum of the products of the binomial coefficients of (1+x)^(n) taken two at a time is

Sum of the products of the binomial coefficients of (1+x)^(n) taken two at a time is

The sum of the binomial coefficients of the 3^(rd),4^(th) terms from the beginning and from the end of (a+x)^(n) is 440 then n=

In the expansion of (3^(-(x)/(4))+3^((sx)/(4)))^(n),n in N if sum of the binomial coefficients is 64 then n is:

Sum of the binomial coefficients in the expansion of ((2x)/(3)+(3)/(2nx^(2)))^(n) is equal to 64. The term independent of x is

In the expansion of (x+y)^(n) ,if the binomial coefficient of the third term is greater by 9 then that of the second term,then the sum of the binomial coefficients of the terms occupying to odd places is

In the expansion of (3^(-(x)/(4))+3^((5x)/(4)))^(n) the sum of the binomial coefficients is 256 and four xx the term with greatest binomial coefficient exceeds the square of the third coefficient then find 4x.

In the expansion of (3^(-(x)/(4))+3^((5x)/(4)))^(n), the sum of the binomial coefficients is 256and four xx the term withgreatest binomial coefficient exceeds the square of the third coefficient then find 4x.
