Integral(sqrt(x)*exp(x), (x, 0, 1/7))
Detail solution

    UpperGammaRule(a=1, e=1/2, context=sqrt(x)*exp(x), symbol=x)

  1. Now simplify:

    xex+πxerfc(x)2x\sqrt{x} e^{x} + \frac{\sqrt{\pi} \sqrt{x} \operatorname{erfc}{\left(\sqrt{- x} \right)}}{2 \sqrt{- x}}

  2. Add the constant of integration:

    xex+πxerfc(x)2x+constant\sqrt{x} e^{x} + \frac{\sqrt{\pi} \sqrt{x} \operatorname{erfc}{\left(\sqrt{- x} \right)}}{2 \sqrt{- x}}+ \mathrm{constant}


The answer is:

xex+πxerfc(x)2x+constant\sqrt{x} e^{x} + \frac{\sqrt{\pi} \sqrt{x} \operatorname{erfc}{\left(\sqrt{- x} \right)}}{2 \sqrt{- x}}+ \mathrm{constant}
