Math:
0. We do google numerical integration.
1. Let's see provocative \$f(x)=c\cdot x^{c-1}\cdot e^{-x^c}=
-\left(e^{-x^c}\right)'\$
2. So, we have \$-\int\limits_0^\infty \ln\left(\frac{c\cdot x^{c-1}\cdot e^{-x^c}}{0.5e^{-x}+5e^{-10x}}\right)\left(e^{-x^c}\right)'dx\$,
we change the variable to \$t=e^{-x^c}\$, \$x^c=-\ln(t)\$, 
\$x=\left(-\ln t\right)^\frac1c\$,
\$t(0)=1\$, \$t(+\infty)=0\$ and the integral is
\$\int\limits_0^1 \ln\left(\frac{c\cdot x(t)^{c-1}\cdot t}{\left(0.5+5e^{-9x(t)}\right)e^{-x(t)}}\right)dt=\$
\$\int\limits_0^1 \left(\ln c+\left(\ln x(t)\right)\cdot(c-1)+ \ln t- \ln\left(0.5+5e^{-9x(t)}\right) +x(t)\right)dt=\$
\$\int\limits_0^1 \left(\ln c+\left(\ln \left(-\ln t\right)\right)\cdot\frac{c-1}{c}+ \ln t- \ln\left(0.5+5e^{-9x(t)}\right) +x(t)\right)dt\$
3. Next we wolframalpha these things:
\$\int\limits_0^1\ln(-\ln t)dt\$, 
\$\int\limits_0^1 (-\ln t)^a dt\$,
\$\int\limits_0^1 \ln t\,dt\$  and do the rest numerically (the latter thing maybe can be done with trapeziums or rectangles or Simpson -- the idea for short submissions).
