Whakaoti mō z
z=\frac{2}{5}+i=0.4+i
Tohaina
Kua tāruatia ki te papatopenga
z\times 5=2+5i
Ko te tau tōpū o tētahi tau matatini a+bi ko \sqrt{a^{2}+b^{2}}. Ko te tau tōpū o 3-4i ko 5.
z=\frac{2+5i}{5}
Whakawehea ngā taha e rua ki te 5.
z=\frac{2}{5}+i
Whakawehea te 2+5i ki te 5, kia riro ko \frac{2}{5}+i.
