Ngā Upane Otinga

Tīkina te uara \cos(45) mai i te ripanga uara pākoki.

$$\frac{100}{\frac{\sqrt{2}}{2}}$$

Whakawehe 100 ki te \frac{\sqrt{2}}{2} mā te whakarea 100 ki te tau huripoki o \frac{\sqrt{2}}{2}.

$$\frac{100\times 2}{\sqrt{2}}$$

Whakangāwaritia te tauraro o \frac{100\times 2}{\sqrt{2}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{2}.

$$\frac{100\times 2\sqrt{2}}{\left(\sqrt{2}\right)^{2}}$$

Ko te pūrua o \sqrt{2} ko 2.

$$\frac{100\times 2\sqrt{2}}{2}$$

Whakareatia te 100 ki te 2, ka 200.

$$\frac{200\sqrt{2}}{2}$$

Whakawehea te 200\sqrt{2} ki te 2, kia riro ko 100\sqrt{2}.

$$100\sqrt{2}$$
