(-1)^.5 is a complex number and follows different rules than real numbers. Learn math, then come back.

sqrt(-1) = i, a special number. Like kedlax said, it's a complex number.

The rule that it violated is that sqrt (x/y)=sqrt(x)/sqrt(y) only when the number is positive.

Yes, Yes, stop embarrasing me already. :p I don't use algerbra in my daily tasks so its a little hard to remember all the niggling little rules, esp. after 4 shots of 151 in my coke.
