Which term is independent of x in the expansion of ?

Question

Philoid · Accepted Answer

To find: the term independent of x in the expansion of?

Formula Used:

A general term, T_r+1 of binomial expansionis given by,

T_r+1 ⁿC_r x^n-r y^r where

ⁿC_r

Now, finding the general term of the expression, , we get

T_r+1⁹C_r

For finding the term which is independent of x,

9-3r=0

r=3

Thus, the term which would be independent of x is T₄

Thus, the term independent of x in the expansion of is T₄ i.e 4^th term
