Kua tāruatia ki te papatopenga
\frac{\left(3+5i\right)\left(1+2i\right)}{\left(1-2i\right)\left(1+2i\right)}
Whakareatia te taurunga me te tauraro ki te haumi hiato o te tauraro, 1+2i.
\frac{\left(3+5i\right)\left(1+2i\right)}{1^{2}-2^{2}i^{2}}
Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
\frac{\left(3+5i\right)\left(1+2i\right)}{5}
Hei tōna tikanga, ko te i^{2} ko -1. Tātaitia te tauraro.
\frac{3\times 1+3\times \left(2i\right)+5i\times 1+5\times 2i^{2}}{5}
Me whakarea ngā tau matatini 3+5i me 1+2i pēnā i te whakarea huarua.
\frac{3\times 1+3\times \left(2i\right)+5i\times 1+5\times 2\left(-1\right)}{5}
Hei tōna tikanga, ko te i^{2} ko -1.
\frac{3+6i+5i-10}{5}
Mahia ngā whakarea i roto o 3\times 1+3\times \left(2i\right)+5i\times 1+5\times 2\left(-1\right).
\frac{3-10+\left(6+5\right)i}{5}
Whakakotahitia ngā wāhi tūturu me ngā wāhi pōhewa ki 3+6i+5i-10.
\frac{-7+11i}{5}
Mahia ngā tāpiri i roto o 3-10+\left(6+5\right)i.
-\frac{7}{5}+\frac{11}{5}i
Whakawehea te -7+11i ki te 5, kia riro ko -\frac{7}{5}+\frac{11}{5}i.
Re(\frac{\left(3+5i\right)\left(1+2i\right)}{\left(1-2i\right)\left(1+2i\right)})
