A half square meter is equal to 0.5 square meters. To calculate the area of a square, you multiply the length by the width. Therefore, if a square has sides that are each 1 meter in length, the area would be 1 square meter. Half of that would be 0.5 square meters.
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.
It is 1/2.
There are 10,000 square meters in a hectare. Therefore, half a hectare would be 5,000 square meters.
√(1/2) can only be simplified 1/√2
