It is just a notation, used to make our calculations easier. Square root of -1 is undefined.

-i/sqrt(2) -i/sqrt(2)

You would get (i square root 2) because you can not square root a negative number, the answer is imaginary. Tmdkiller: Square root is NOT applicable to any Negative numbers eg -1 ,-2,-3 etc You would get an "Error 2" on a scientific Calculator anyway. =) editted by razakhan squre root of -2 is 2i (where "i" is "iota" represents imaginary or complex number......

The square root of 1/9 is 1/3 because the square root of 1 is 1 and the square root of 9 is 3.

a quarter is 1/4 and square root of 1/4 is square root (1/4)=square root of 1 divided by square root of 4 which is 1 divided by 2. So the answer is 1/2
