MCQ
$\int_{}^{} {({e^{a\log x}} + {e^{x\log a}})dx} = $
  • A
    ${x^{a + 1}} + \frac{{{a^x}}}{{\log a}} + c$
  • B
    $\frac{{{x^{a + 1}}}}{{a + 1}} + {a^x}\log a + c$
  • $\frac{{{x^{a + 1}}}}{{a + 1}} + \frac{{{a^x}}}{{\log a}} + c$
  • D
    None of these

Answer

Correct option: C.
$\frac{{{x^{a + 1}}}}{{a + 1}} + \frac{{{a^x}}}{{\log a}} + c$
c
(c) $\int_{}^{} {({e^{a\log x}} + {e^{x\log a}})\,dx} = \int_{}^{} {({e^{{{\log }_e}{x^a}}} + {e^{{{\log }_e}{a^x}}})\,dx} $
$ = \int_{}^{} {({x^a} + {a^x})\,dx} = \frac{{{x^{a + 1}}}}{{a + 1}} + \frac{{{a^x}}}{{\log a}} + c$.
