Ngā Hipanga Rongoā Poto

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 2 ki te \frac{5}{5}.

$$\frac{\frac{2\times 5}{5}-\frac{2\sqrt{30}}{5}}{\frac{2}{5}}$$

Tā te mea he rite te tauraro o \frac{2\times 5}{5} me \frac{2\sqrt{30}}{5}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{2\times 5-2\sqrt{30}}{5}}{\frac{2}{5}}$$

Mahia ngā whakarea i roto o 2\times 5-2\sqrt{30}.

$$\frac{\frac{10-2\sqrt{30}}{5}}{\frac{2}{5}}$$

Whakawehe \frac{10-2\sqrt{30}}{5} ki te \frac{2}{5} mā te whakarea \frac{10-2\sqrt{30}}{5} ki te tau huripoki o \frac{2}{5}.

$$\frac{\left(10-2\sqrt{30}\right)\times 5}{5\times 2}$$

Me whakakore tahi te 5 i te taurunga me te tauraro.

$$\frac{-2\sqrt{30}+10}{2}$$

Whakawehea ia wā o -2\sqrt{30}+10 ki te 2, kia riro ko 5-\sqrt{30}.

$$5-\sqrt{30}$$

Tauwehe

$$5-\sqrt{30}$$
