By pernici:

I modified `radsimp` so that it can simplify denominators with 3 roots, I put the code in my branch and-per (but it does not run there,
use it here)

```
>>> from sympy import *
>>> z = 1/(1 + sqrt(2) + sqrt(3) + sqrt(5))
>>> a = radsimp(z); a
(-34*sqrt(10) - 26*sqrt(15) - 55*sqrt(3) - 61*sqrt(2) + 14*sqrt(30) + 93 + 46*sqrt(6) + 53*sqrt(5))/71
>>> (z - a).evalf()
.0e-127
```
