The other day, I was explaining something to a student regarding solving a
simple algebra problem.
The solution to which is easily found. All four that is! However my version of
Mathematica only gave the two real. Is there a simple explanation for this?
Also, Mathematica gives the solution to x^(1/2)= -16 as 256. Now, is this a
"principle root" problem and are the two possibly related? Any insights would
be appreciated for this little enigma.
