જો $0 < y < 2^{1/3}$ અને $x(y^3 - 1) = 1$ હોય,તો $\frac{2}{x} + \frac{2}{3x^3} + \frac{2}{5x^5} + \dots$ ની કિંમત શોધો:

  • A
    $\log \left( \frac{y^3}{2 - y^3} \right)$
  • B
    $\log \left( \frac{y^3}{1 - y^3} \right)$
  • C
    $\log \left( \frac{2y^3}{1 - y^3} \right)$
  • D
    $\log \left( \frac{y^3}{1 - 2y^3} \right)$
