Integration - Integration of Power Functions

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

  1. \(9x^4-4x+\dfrac{3}{x^2}+6\)
  2. \(5x^{\frac{5}{2}}-2x^{-\frac{3}{2}}+\dfrac{7}{x}\)
  3. \(\frac{3x^6-2x^3+\sqrt{x}-x^{-2}}{x^2}\)
  4. \(\left(\frac{5}{(4x-1)^2}\right)^3+\left(\frac{2}{\sqrt{1-3x}}\right)\)
