    Well it doesn't have a real answer. It ends up as \[\large -4*-4=16\] not \[\large -4*-4=-16\] The only way to solve this is to add on an imaginary number i.

    it is not \[\sqrt{-16}\] it is \[-\sqrt{16}\] (well even this is not quite true sqrt 16 is +4 or -4 the negative of those is obvious BUT -sqrt(16) is still +4 OR -4

    @LegendarySadist there is no need for imaginary solutions here
