Kua tāruatia ki te papatopenga
\frac{\left(3-3i\right)i}{7i^{2}}
Me whakarea tahi te taurunga me te tauraro ki te wae pohewa i.
\frac{\left(3-3i\right)i}{-7}
Hei tōna tikanga, ko te i^{2} ko -1. Tātaitia te tauraro.
\frac{3i-3i^{2}}{-7}
Whakareatia 3-3i ki te i.
\frac{3i-3\left(-1\right)}{-7}
Hei tōna tikanga, ko te i^{2} ko -1.
\frac{3+3i}{-7}
Mahia ngā whakarea i roto o 3i-3\left(-1\right). Whakaraupapatia anō ngā kīanga tau.
-\frac{3}{7}-\frac{3}{7}i
Whakawehea te 3+3i ki te -7, kia riro ko -\frac{3}{7}-\frac{3}{7}i.
Re(\frac{\left(3-3i\right)i}{7i^{2}})
Me whakarea tahi te taurunga me te tauraro o \frac{3-3i}{7i} ki te wae pohewa i.
Re(\frac{\left(3-3i\right)i}{-7})
Hei tōna tikanga, ko te i^{2} ko -1. Tātaitia te tauraro.
Re(\frac{3i-3i^{2}}{-7})
Whakareatia 3-3i ki te i.
Re(\frac{3i-3\left(-1\right)}{-7})
Hei tōna tikanga, ko te i^{2} ko -1.
Re(\frac{3+3i}{-7})
Mahia ngā whakarea i roto o 3i-3\left(-1\right). Whakaraupapatia anō ngā kīanga tau.
Re(-\frac{3}{7}-\frac{3}{7}i)
Whakawehea te 3+3i ki te -7, kia riro ko -\frac{3}{7}-\frac{3}{7}i.
-\frac{3}{7}
