In any binomial expansion,the number of terms are

If n is a positive integer, then the number of terms in the expansion of (x+a)^n is

With the help of bionomial expansion, show that (4^(n)-3n) is always leaves remainder 1, when divided by 9.

Consider the expansion of (x+1/x)^10 The number of terms in the expansion is……

Consider the binomial expansion of (sqrt(x)+(1/(2x^(1/4))))^n n in NN, where the terms of the expansion are written in decreasing powers of x. If the coefficients of the first three terms form an arithmetic progression then the statement(s) which hold good is(are) (A) total number of terms in the expansion of the binomial is 8 (B) number of terms in the expansion with integral power of x is 3 (C) there is no term in the expansion which is independent of x (D) fourth and fifth are the middle terms of the expansion
