Tauwehea te 8=2\times 4. Tuhia anō te pūtake rua o te hua \sqrt{2\times 4} hei hua o ngā pūtake rua \sqrt{2}\sqrt{4}.

$$\sqrt{2}\sqrt{4}\sqrt{2}=\sqrt{2\times 2}\text{ and }\sqrt{2\times 2}=\sqrt{16}$$

Whakareatia te \sqrt{2} ki te \sqrt{2}, ka 2.

$$2\sqrt{4}=\sqrt{2\times 2}\text{ and }\sqrt{2\times 2}=\sqrt{16}$$

Tātaitia te pūtakerua o 4 kia tae ki 2.

$$2\times 2=\sqrt{2\times 2}\text{ and }\sqrt{2\times 2}=\sqrt{16}$$

Whakareatia te 2 ki te 2, ka 4.

$$4=\sqrt{2\times 2}\text{ and }\sqrt{2\times 2}=\sqrt{16}$$

Whakareatia te 2 ki te 2, ka 4.

$$4=\sqrt{4}\text{ and }\sqrt{2\times 2}=\sqrt{16}$$

Tātaitia te pūtakerua o 4 kia tae ki 2.

$$4=2\text{ and }\sqrt{2\times 2}=\sqrt{16}$$

Whakatauritea te 4 me te 2.

$$\text{false}\text{ and }\sqrt{2\times 2}=\sqrt{16}$$

Whakareatia te 2 ki te 2, ka 4.

$$\text{false}\text{ and }\sqrt{4}=\sqrt{16}$$

Tātaitia te pūtakerua o 4 kia tae ki 2.

$$\text{false}\text{ and }2=\sqrt{16}$$

Tātaitia te pūtakerua o 16 kia tae ki 4.

$$\text{false}\text{ and }2=4$$

Whakatauritea te 2 me te 4.

$$\text{false}\text{ and }\text{false}$$

Ko te kōmititanga tōrunga o \text{false} me \text{false} ko \text{false}.
