Answer & Solution

Correct Answer

(D) \(2\)

Step-by-step Solution

Detailed explanation

\(\mathrm{R}\left\{(x, y): \max \left(0, \log _{e} x\right) \leq y \leq 2^{x}, \frac{1}{2} \leq x \leq 2\right\}\) \(\int_{\frac{1}{2}}^{2} 2^{x} \,d x-\int_{1}^{2} \ln x\, d x\) \(\Rightarrow\left[\frac{2^{x}}{\ln 2}\right]_{1 / 2}^{2}-[x \ln x-x]_{1}^{2}\)…
