Integration - Integration of Exponential Functions

Integrate the following exponential expressions with respect to \(x\):

  1. \(\displaystyle\displaystyle \displaystyle\int \mathrm{e}^{3x+2} \, \mathrm{d}x\)
  2. \(\displaystyle\displaystyle \displaystyle\int \frac{\mathrm{e}^{5x}+2}{\mathrm{e}^{5x}} \, \mathrm{d}x\)
  3. \(\displaystyle\displaystyle \displaystyle\int \frac{(\mathrm{e}^{3x}-\mathrm{e}^{x})^2}{\mathrm{e}^{x}} \, \mathrm{d}x\)
  4. \(\displaystyle\displaystyle \displaystyle\int \frac{2-\mathrm{e}^{3-2x}}{\mathrm{e}^{3-2x}} \, \mathrm{d}x\)
