How do you simplify negative radicals?
Take for instance sqrt(108)...
You need imaginary numbers (i = sqrt(1)), but with that, it's usually pretty simple.
Your example: sqrt(108) = sqrt(1 * 108) = sqrt(1)*sqrt(108) = i*sqrt(108)
Of course, if you had something like sqrt(1  sqrt(2)), you'd get sqrt(1  i*sqrt(2)), which is still a complex number, but isn't quite so simple.
All right thanks for the help.
