A number to the one half power is the square root.
There are two square roots of i: (-1/square root 2)(1+i) and (1/square root 2)(1+i) so these are i to the one half power. Now to find -i to the one half power, multiply either of these by i, since i2 is -1. So (-i/square root 2)(1+i) and (i/square root 2)(1+i) are the square roots of -i. Verify this by direct multiplication.
