Find the term independent of x (constant...

Find the term independent of x (constant term) in the following expansion:
`(i) (x^(2)-(1)/(3x))^(9) " "(ii) (x-(1)/(x))^(10)`
`(iii) (3x-(2)/(x^(2)))^(18) " "(iv) (1)/(x^(n))(1+x)^(2n)`
`(V)(3sqrt(x)+(1)/(2(3sqrt(x))))^(18)" "(vi)((3x^(2))/(2)-(1)/(3x))^(6)`

Text Solution

Verified by Experts

The correct Answer is:
`(i) (28)/(243) " "(ii)-252 " "(iii) -^(15)C_(5).3^(10).2^(5)`
`(iv) ^(2n)C_(n) " "(v) (12155)/(128)" "(iv) (5)/(12)`
