Ngā Upane Otinga

Whakarohaina te \left(-2\sqrt{5}\right)^{2}.

$$2\left(-2\right)^{2}\left(\sqrt{5}\right)^{2}+\sqrt{\left(-3\right)^{2}}$$

Tātaihia te -2 mā te pū o 2, kia riro ko 4.

$$2\times 4\left(\sqrt{5}\right)^{2}+\sqrt{\left(-3\right)^{2}}$$

Ko te pūrua o \sqrt{5} ko 5.

$$2\times 4\times 5+\sqrt{\left(-3\right)^{2}}$$

Whakareatia te 4 ki te 5, ka 20.

$$2\times 20+\sqrt{\left(-3\right)^{2}}$$

Whakareatia te 2 ki te 20, ka 40.

$$40+\sqrt{\left(-3\right)^{2}}$$

Tātaihia te -3 mā te pū o 2, kia riro ko 9.

$$40+\sqrt{9}$$

Tātaitia te pūtakerua o 9 kia tae ki 3.

$$40+3$$

Tāpirihia te 40 ki te 3, ka 43.
