Kua tāruatia ki te papatopenga
1.2+0.7i-\left(2i\left(-1\right)+2\left(-1\right)i^{2}\right)
Whakareatia 2i ki te -1-i.
1.2+0.7i-\left(2i\left(-1\right)+2\left(-1\right)\left(-1\right)\right)
Hei tōna tikanga, ko te i^{2} ko -1.
1.2+0.7i-\left(2-2i\right)
Mahia ngā whakarea i roto o 2i\left(-1\right)+2\left(-1\right)\left(-1\right). Whakaraupapatia anō ngā kīanga tau.
1.2-2+\left(0.7-\left(-2\right)\right)i
Tangohia te 2-2i i te 1.2+0.7i mā te tango i ngā wāhi tūturu me ngā wāhi pohewa hāngai.
-0.8+2.7i
Tango 2 mai i 1.2. Tango -2 mai i 0.7.
