Issue with CAS solve command?

RE: Issue with CAS solve command?
There are two bugs here: the first one happens when you copy/paste, the EQW translates ^.5 to sqrt(), which makes the equation an exact equation. Then because of the quotes, sqrt() is not evaled to pow(,1/2) and not recognized as a fractional powers by the exact solver, and that raises at some point an assertion failure > crash. I've fixed the exact solver not to crash, but it will return an empty list for the exact equation if quotes are present, because the CAS expects sqrt to be evaled to pow(,1/2). A workaround is either to remove quotes or enter an approx number elsewhere in your equation, for example for 10. or 5.5, so that the EQW does not convert your equation to something exact.
