Just came across a question that I'm not too sure on
$\int \frac {-6}{(x\sqrt{x})}\, dx$

-12/[5(x^2.5)] + C

also

§ a^x dx = (a^x)/ln(a) + C

pretty sure that isnt the answer..

As superflya said, take out the constant:

$\int -\frac{6}{x\sqrt{x}} dx = -6 \int \frac{1}{x^{\frac{3}{2}}} dx = -6 \int x^{-\frac{3}{2}} dx = -6 \cdot \frac{x^{-\frac{1}{2}}}{-\frac{1}{2}} = -6 \cdot \frac{\frac{1}{\sqrt{x}}}{-\frac{1}{2}} = \frac{12}{\sqrt{x}} + C$
