Find the 15th term in the expansion of "...

Find the 15th term in the expansion of `"("sqrt(x)-sqrt(y)")"^(17)`

Text Solution

Verified by Experts

The correct Answer is:
N/a
`T_(15)=T_(14+1)`
`=^(17)C_(14)(sqrt(x))^(17-14)."("-sqrt(y)")"^(14)`
`(|ul17)/(|ul14|ul3).x^(3//2).y^(7)`
`(15xx16xx17)/(1xx2xx3).x^(3//2).y^(7)`
`=680 .x^(3//2).y^(7)`
