What is the square root of - 0.50?
there is no real square root of a minus number (think about it, minus x minus = plus, plus x plus=plus, and you can't have a minus x plus if it's a square root). However, there is an imaginary root which is "1/2i", where "i" represents the square root of -1. This number doesn't actually "exist" as such, it is just a theory which makes doing maths easier. However if you're not familiar with the concept of "i", you're probably not meant to end up with a minus square root (anything below A level further maths you don't usually need "i") . Check your calculations again.
