Write the 4^th term from the end in the expansion of

To find: 4^th term from the end 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

Total number of terms in the expansion is 8

Thus, the 4^th term of the expansion is T₅ and is given by,

T₅ ⁷C₅

T₅

T₅

T₅

Thus, a 4^th term from the end in the expansion of is T₅
