If the number of terms in the expansion of 
, x ≠ 0, is 28, then the sum of the coefficients of all the terms in this expansion, is
Text Solution
Verified by ExpertsThe correct answer is:
C
Theortically the number of terms are 2N + 1 (i.e. odd) But As the number of terms being odd hence considering that number clubbing of terms is done hence the solutions follwos :
Number of terms = n+2 C 2 = 28 ∴ n = 6
sum of cofficient = 3 n = 3 6 = 729
put x = 1
