For a real number x, √√(-x) equals :
a) +x b) -x c) complex d) pure imaginary
√-1 = i
The Attempt at a Solution
Here is what i did:
If x is a positive real number then the answer comes out to be x^0.25 * √i (now what is square root of i equal to?)
But if x is a negative real number then the solution would be :
I don't know what to do next, any help would be appreciated.
