2] $\displaystyle \int \displaystyle{\frac{x^2 + x}{x}} (dx) $

3] $\displaystyle \int 2\sqrt{x} - \displaystyle{\frac{3}{x^3}} (dx) $

4] $\displaystyle \int \sqrt{x} - \displaystyle{\frac{2}{x^2}} (dx) $

5] $\displaystyle \int \displaystyle{\frac{4}{x^3}} - ^7\sqrt{x} (dx) $

Here are the answers to a few I could come up with:

1] $\displaystyle \displaystyle{\frac{1}{x^3}} - \displaystyle{\frac{1}{x}} + c $

2] $\displaystyle \displaystyle{\frac{x^3}{3}} + \displaystyle{\frac{x^2}{2}} + c $

3] $\displaystyle \displaystyle{\frac{4x^3/2}{3}} + \displaystyle{\frac{3}{x}} + c $

This is all I could do can you please help with the rest? It's the first time I've done latex as I say so I'm sorry if it's unreadable.
