    If \[y={{e}^{(1+{{\log }_{e}}x)}}\], then the value of \[\frac{dy}{dx}=\] [MP PET 1996; Pb. CET 2001]

    A)            e

    B)            1

    C)            0

    D)            \[{{\log }_{e}}x\,\,{{e}^{{{\log }_{e}}ex}}\]

    Correct Answer: A

    Solution :

               \[y={{e}^{1+{{\log }_{e}}x}}={{e}^{1}}.{{e}^{{{\log }_{e}}x}}=e.x\Rightarrow \frac{dy}{dx}=e\].
