CAS: approx. sqrt?

RE: CAS: approx. sqrt?
Thanks for the explanation,
but what about the 3root and 4root expressions? They stay in exact form. Why not have sqrt(complex #) simply also rewritten as e^(1/2*ln(complex number)? Or just leave it as sqrt(Complex #)? Will that really lead to too complicated, exact expressions further on? If so, flashing the warning makes sense (as a suggestion), but the user can always hit the approx key anyway (at any time). I don't think that the CAS system should approximate by default   the beauty of CAS is to enable exact computations.
