Ok this is a serious question
why can you not get the square root of a negative number? Plz explain
(CPhill or hecticar)
no offense to the ppls but you they make sense the best to me
You can take the square root of a negative, but it's not a real number...
The square root of -1 is defined as "i" [ "i" as in, "imaginary" ]
So, for instance
√ [ -4 ] = √4 *√-1 = 2 * i = 2i
I'll start with an example. The square root of 64 is 8, so that means that 8*8 is 64. The numbers multiplied always have to be exactly the same to be a square root.
If you tried to do the square root of -48 there would be no answer because -8*-8 equals 64.
A negative times a negative, or a positive times a positive will always be positive, therefore they will never be negative.
