Ngā Upane Otinga

Tātaihia te -\sqrt{5} mā te pū o 2, kia riro ko \left(\sqrt{5}\right)^{2}.

$$1\left(\sqrt{5}\right)^{2}-\sqrt{16}+\sqrt{\left(-2\right)^{2}}$$

Tātaitia te pūtakerua o 16 kia tae ki 4.

$$1\left(\sqrt{5}\right)^{2}-4+\sqrt{\left(-2\right)^{2}}$$

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

$$1\left(\sqrt{5}\right)^{2}-4+\sqrt{4}$$

Tātaitia te pūtakerua o 4 kia tae ki 2.

$$1\left(\sqrt{5}\right)^{2}-4+2$$

Tāpirihia te -4 ki te 2, ka -2.

$$1\left(\sqrt{5}\right)^{2}-2$$

Ko te pūrua o \sqrt{5} ko 5.

$$1\times 5-2$$

Whakareatia te 1 ki te 5, ka 5.

$$5-2$$

Tangohia te 2 i te 5, ka 3.

$$3$$
