Ngā Hipanga Rongoā Poto

Whakareatia te 5 ki te 4, ka 20.

$$\frac{1\sqrt{20}}{7}+3$$

Tauwehea te 20=2^{2}\times 5. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 5} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{5}. Tuhia te pūtakerua o te 2^{2}.

$$\frac{1\times 2\sqrt{5}}{7}+3$$

Whakareatia te 1 ki te 2, ka 2.

$$\frac{2\sqrt{5}}{7}+3$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 3 ki te \frac{7}{7}.

$$\frac{2\sqrt{5}}{7}+\frac{3\times 7}{7}$$

Tā te mea he rite te tauraro o \frac{2\sqrt{5}}{7} me \frac{3\times 7}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2\sqrt{5}+3\times 7}{7}$$

Mahia ngā whakarea i roto o 2\sqrt{5}+3\times 7.

$$\frac{2\sqrt{5}+21}{7}$$

Tauwehe

$$\frac{2 \sqrt{5} + 21}{7} = 3.63887656499994$$
