CAS : strange error on simplify

[Helge Gabert]

I wouldn't call that an error- - it is just a warning message - - although times 4, which doesn't appear to be necessary.

Assuming that by sq() you mean square root [sqrt()], if you expand() your expression first, and then simplify(), you will not receive those 4 warning messages, regardless whether you have the CAS settings on Maximum or Minimum simplification.
