Whakaoti i te (1-1/3)(-6/5+3i)

$$( 1 - \frac { 1 } { 3 } ) ( - \frac { 6 } { 5 } + 3 i )$$

Aromātai

$$-\frac{4}{5}+2i=-0.8+2i$$

Ngā Upane Otinga

Me tahuri te 1 ki te hautau \frac{3}{3}.

$$\left(\frac{3}{3}-\frac{1}{3}\right)\left(-\frac{6}{5}+3i\right)$$

Tā te mea he rite te tauraro o \frac{3}{3} me \frac{1}{3}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{3-1}{3}\left(-\frac{6}{5}+3i\right)$$

Tangohia te 1 i te 3, ka 2.

$$\frac{2}{3}\left(-\frac{6}{5}+3i\right)$$

Whakareatia \frac{2}{3} ki te -\frac{6}{5}+3i.

$$\frac{2}{3}\left(-\frac{6}{5}\right)+\frac{2}{3}\times \left(3i\right)$$

Mahia ngā whakarea.

$$-\frac{4}{5}+2i$$

Wāhi Tūturu

$$-\frac{4}{5} = -0.8$$

Ngā Upane Otinga

Me tahuri te 1 ki te hautau \frac{3}{3}.

$$Re(\left(\frac{3}{3}-\frac{1}{3}\right)\left(-\frac{6}{5}+3i\right))$$

Tā te mea he rite te tauraro o \frac{3}{3} me \frac{1}{3}, me tango rāua mā te tango i ō raua taurunga.

$$Re(\frac{3-1}{3}\left(-\frac{6}{5}+3i\right))$$

Tangohia te 1 i te 3, ka 2.

$$Re(\frac{2}{3}\left(-\frac{6}{5}+3i\right))$$

Whakareatia \frac{2}{3} ki te -\frac{6}{5}+3i.

$$Re(\frac{2}{3}\left(-\frac{6}{5}\right)+\frac{2}{3}\times \left(3i\right))$$

Mahia ngā whakarea i roto o \frac{2}{3}\left(-\frac{6}{5}\right)+\frac{2}{3}\times \left(3i\right).

$$Re(-\frac{4}{5}+2i)$$

Ko te wāhi tūturu o -\frac{4}{5}+2i ko -\frac{4}{5}.

$$-\frac{4}{5}$$
