$\int \frac{x+1}{x(1+x e^x)^2} \,d x=$ (જ્યાં $C$ એ સંકલનનો અચળાંક છે.)

  • A
    $\log (1+x e^x)+\frac{1}{1+x e^x}+C$
  • B
    $\log \left(\frac{x e^x}{1+x e^x}\right)+\frac{1}{1+x e^x}+C$
  • C
    $\log \left(\frac{x e^x}{1+x e^x}\right)+C$
  • D
    $\log \left(\frac{x e^x}{1+x e^x}\right)-\frac{1}{1+x e^x}+C$
