In general, the desired simplification is true, if the variable a is
positive. When setting the option variable radexpand to true, Maxima
assumes all variables to be real and positive:
(%i2) radexpand:all$
(%i3) (a^b)^c;
(%o3) a^(b*c)
(%i4) reset(radexpand)$
A second way is to assume the variable a to be positive:
(%i7) assume(a>0)$
(%i8) (a^b)^c;
(%o8) a^(b*c)
