$\int_{}^{} {\frac{{3{x^3} - 2\sqrt x }}{x}} dx = $
  • A
    ${x^3} - \sqrt x + c$
  • B
    ${x^3} + \sqrt x + c$
  • C
    ${x^3} - 2\sqrt x + c$
  • ${x^3} - 4\sqrt x + c$

Answer

Correct option: D.
${x^3} - 4\sqrt x + c$
d
(d) $\int_{}^{} {\frac{{3{x^3} - 2\sqrt x }}{x}\,dx} = \int_{}^{} {3{x^2}dx} - 2\int_{}^{} {{x^{ - 1/2}}dx} = {x^3} - 4\sqrt x + c$.
