Whakaoti i te 0.5*sqrt{12}*sqrt{6}*sqrt{2}+0.2

$$0.5 \cdot \sqrt { 12 } \cdot \sqrt { 6 } \cdot \sqrt { 2 } + 0.2$$

Aromātai

$$6.2$$

Ngā Upane Otinga

Tauwehea te 12=6\times 2. Tuhia anō te pūtake rua o te hua \sqrt{6\times 2} hei hua o ngā pūtake rua \sqrt{6}\sqrt{2}.

$$0.5\sqrt{6}\sqrt{2}\sqrt{6}\sqrt{2}+0.2$$

Whakareatia te \sqrt{6} ki te \sqrt{6}, ka 6.

$$0.5\times 6\sqrt{2}\sqrt{2}+0.2$$

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

$$0.5\times 6\times 2+0.2$$

Whakareatia te 0.5 ki te 6, ka 3.

$$3\times 2+0.2$$

Whakareatia te 3 ki te 2, ka 6.

$$6+0.2$$

Tāpirihia te 6 ki te 0.2, ka 6.2.

$$6.2$$

Tauwehe

$$\frac{31}{5} = 6\frac{1}{5} = 6.2$$
