Aromātai

$$\frac{\sqrt{1786}}{94}\approx 0.449586098$$

Ngā Upane Otinga

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

$$\sqrt{\frac{19}{4+3^{2}+9^{2}}}$$

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$\sqrt{\frac{19}{4+9+9^{2}}}$$

Tāpirihia te 4 ki te 9, ka 13.

$$\sqrt{\frac{19}{13+9^{2}}}$$

Tātaihia te 9 mā te pū o 2, kia riro ko 81.

$$\sqrt{\frac{19}{13+81}}$$

Tāpirihia te 13 ki te 81, ka 94.

$$\sqrt{\frac{19}{94}}$$

Tuhia anō te pūtake rua o te whakawehenga \sqrt{\frac{19}{94}} hei whakawehenga o ngā pūtake rua \frac{\sqrt{19}}{\sqrt{94}}.

$$\frac{\sqrt{19}}{\sqrt{94}}$$

Whakangāwaritia te tauraro o \frac{\sqrt{19}}{\sqrt{94}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{94}.

$$\frac{\sqrt{19}\sqrt{94}}{\left(\sqrt{94}\right)^{2}}$$

Ko te pūrua o \sqrt{94} ko 94.

$$\frac{\sqrt{19}\sqrt{94}}{94}$$

Hei whakarea \sqrt{19} me \sqrt{94}, whakareatia ngā tau i raro i te pūtake rua.

$$\frac{\sqrt{1786}}{94}$$
