Let complex numbers zA and zB correspond to points A and B on the complex plane respectively. Then the vector corresponding to the sum of 1zA and zB is suitable for parallelogram rule or triangle rule of vector addition; 2|zA-zB| denotes point A and B. The distance; 3zA, zB product or quotient corresponding vector suitable for vector multiplication, division of the rotation and expansion law; 4 equation xn = b (b ∈ C) the root of the corresponding point are
