5 amplifiers in 30 minutes is the same as 10 amplifiers per hour. Divide 230 amplifiers by 10 amplifiers (which is how many you can make per hour) to get 23 hours [the answer].

E^(x/2) /(e^(x/3) +1)
nevsk [136]

\int e^{x/2} /(e^{x/3} +1) dx

start with substituting z=e^x

z=e^x\\dz=e^x dx\\\int \frac{dz}{z^{5/6}+z^{1/2}}

then substitute u = z^(1/6):

u=z^{1/6}\\dz=6 z^{5/6}du\\6 \int \frac{u^2}{u^2+1}du

that integral has a standard form that can be looked up in integral tables, it has the following solution:

6(u - \tan^{-1} u) + \mbox{constant}

substituting back the the variable z and then x you get the final solution:

6 e^{x/6} - 6 \tan^{-1}(e^{x/6}) + \mbox{constant}
