integrate a^(x)e^(x) dx

We haven't done integrations by part so I am not sure if that would be helpful for this question. I do not see any u substituion so I am not sre where to begin. I have tried taking natural logs and have gotten nowhere. Any infomation that could lead me in the right direction would be greatly appreciated

Try converting to a different form, then see what you notice from there.
 
what type of form, I don't really know how to go about making it easier
 
Try converting ax to e to the appropriate power.

a = eln a, as long as a > 0 and not equal to 1.
 
Prove $$\int\limits_0^{\sqrt2/4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx = \frac{\pi^2}{8}.$$ Let $$I = \int\limits_0^{\sqrt 2 / 4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx. \tag{1}$$ The representation integral of ##\arcsin## is $$\arcsin u = \int\limits_{0}^{1} \frac{\mathrm dt}{\sqrt{1-t^2}}, \qquad 0 \leqslant u \leqslant 1.$$ Plugging identity above into ##(1)## with ##u...
