  1. A \(\frac{1-x}{x}\)
  2. B \(\frac{1}{x}\)
  3. C \(\frac{x}{1+x}\)
  4. D \(\frac{1+x}{x}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\frac{1-x}{x}\)

Step-by-step Solution

Detailed explanation

It is given that, \(\begin{array}{lll} & x =e^{y+e^{y+e^{y+\ldots}}} \\ \Rightarrow & x =e^{y+x} \\ \Rightarrow & \log _e x =x+y \Rightarrow y=\log _e x-x \end{array}\) On differentiating both sides with respect to ' \(x\) ', we get…
