Expand of the expression : `(x/3+1/x)^5`

Text Solution

Verified by Experts

The correct Answer is:
N/a

`((x)/(3)+(1)/(x))^(5)`
`=^(5)C_(0)((x)/(3))^(5)((1)/(x))^(0)+^(5)C_(1)((x)/(3))^(4)((1)/(x))^(1)`
`+^(5)C_(2)((x)/(3))^(3)((1)/(x))^(2)+^(5)C_(3)((x)/(3))^(2)((1)/(x))^(3)`
`+^(5)C_(4)((x)/(3))^(1)((1)/(x))^(4)+^(5)C_(5)((x)/(3))^(0)((1)/(x))^(5)`
`=[(x^(5))/(243)]+[(5)/(1)xx(x^(4))/(81)xx(1)/(x)]+[(5xx4)/(2xx1)xx(x^(3))/(27)xx(1)/(x^(2))]`
`+[(5xx4)/(2xx1)xx(x^(2))/(9)xx(1)/(x^(3))]+[(5)/(1)xx(x)/(3)xx(1)/(x^(4))]`
`+[1xx(1)/(x^(4))]`
`=(x^(5))/(243)+(5x^(3))/(81)+(10x)/(27)+(10)/(9x)+(5)/(3x^(3))+(1)/(x^(5))`
