Answer & Solution

Correct Answer

(D) \(e^2 \log \sqrt{2}\)

Step-by-step Solution

Detailed explanation

Given \(\lim _{x \rightarrow 0} \frac{\left(2^x-1\right)(1+\sin x)^{\frac{2}{\sin x}}}{\log (1+2 x)}\) Differentiate w.r.t. ' \(\mathrm{x}\) ' both sides \[ f^{\prime}(x)=\frac{\left(e^{-x} \cos x-e^{-x} \sin x\right) \log x-e^{-x} \frac{\sin x}{x}}{\left(\log e^x\right)^2} \]…
