Evaluate the following integrals : `intsqrt(x)(x^3-2/x)dx`

Text Solution

Verified by Experts

`int sqrt x(x^3-2/x) dx`
`=int x^(3+1/2)-2x^(-1+1/2)`
`=int (x^((6+1)/2) -2x^((-2+1)/2))dx`
`=int (x^(7/2)-2x^(-1/2))dx`
We know that `int x^n dx=frac{x^(n+1)}{n+1}`
`=frac{x^(frac{7+2}{2})}{frac{7+2}{2}}-2frac{x^(frac{-1+2}{2})}{frac{-1+2}{2}}+C`
`=2/9 x^(9/2)-4 sqrt x+C`
