Ngā Upane Otinga

Tātaihia te 4 mā te pū o 2, kia riro ko 16.

$$\frac{-4}{\sqrt{16-4+1\times 2}}$$

Tangohia te 4 i te 16, ka 12.

$$\frac{-4}{\sqrt{12+1\times 2}}$$

Whakareatia te 1 ki te 2, ka 2.

$$\frac{-4}{\sqrt{12+2}}$$

Tāpirihia te 12 ki te 2, ka 14.

$$\frac{-4}{\sqrt{14}}$$

Whakangāwaritia te tauraro o \frac{-4}{\sqrt{14}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{14}.

$$\frac{-4\sqrt{14}}{\left(\sqrt{14}\right)^{2}}$$

Ko te pūrua o \sqrt{14} ko 14.

$$\frac{-4\sqrt{14}}{14}$$

Whakawehea te -4\sqrt{14} ki te 14, kia riro ko -\frac{2}{7}\sqrt{14}.

$$-\frac{2}{7}\sqrt{14}$$
