    \[\int_{{}}^{{}}{{{e}^{x\log a}}.\ {{e}^{x}}\ dx}\]is equal to [Kerala (Engg.) 2005]

    A)            \[{{(ae)}^{x}}+c\]

    B)            \[\frac{{{(ae)}^{x}}}{\log (ae)}+c\]

    C)            \[\frac{{{e}^{x}}}{1+\log a}+c\]

    D)            None of these

    Correct Answer: B

    Solution :

               \[\int_{{}}^{{}}{{{e}^{x\log a}}{{e}^{x}}dx}=\int_{{}}^{{}}{{{e}^{\log {{a}^{x}}}}.\,{{e}^{x}}dx}=\int_{{}}^{{}}{{{a}^{x}}{{e}^{x}}dx}\]                             \[=\int_{{}}^{{}}{{{(ae)}^{x}}dx}=\frac{{{(ae)}^{x}}}{\log (ae)}+C.\]
