Ans:
Hello Student,
Please find answer to your question below

$I = \int \sqrt{x}(x^3-\frac{2}{x}) dx$
$I = \int (x^{7/2}-\frac{2}{\sqrt{x}}) dx$
$I = \int x^{7/2}dx-\int \frac{2}{\sqrt{x}} dx$
$I = \frac{x^{\frac{7}{2}+1}}{\frac{7}{2}+1}- \int \frac{2}{\sqrt{x}}dx$
$I = \frac{2x^{\frac{9}{2}}}{9} - \int \frac{2}{\sqrt{x}}dx$
$I = \frac{2x^{\frac{9}{2}}}{9} - 4\sqrt{x}+c$
