Hello Bastian,
this simplification is valid only for positive x in general (try x = -1).
In [1]: x = Symbol("x", positive=True)
In [2]: (x**2)**(3*numbers.One()/2)
Out[2]:
3
x
for real x, it simplifies to absolute value
In [3]: x = Symbol("x", real=True)
In [4]: (x**2)**(3*numbers.One()/2)

Hi, try srepr(Rational(1,2))

Hello,
just FYI, there are already random number objects in sympy,
you can access them this way:
>>> from sympy.statistics import *
>>> x = Normal(0,1)
>>> x.random()
-0.181742214115
>>> a = x.random(10)
>>> print a
Sample([-1.47958009923, -1.23521203179, -0.783418473091,
-0.0760736376295, -0.046
