No, I'm sorry if I wasn't clear enough

Ans^(1/3) returns a different root than (-1.2)^(1/3). That's all.

Both of those expressions yield 0.531329284592+0.920289316461*i in Home, and almost the same in CAS (real part differs by one ULP). Make sure that you're actually typing all the parentheses that you indicated above. Turning off Textbook Display mode (page 2 of Home Settings) may make it easier to see what's happening.
