Whakaoti i te frac{sqrt{2*5}*213/18*0.25}{18}=

$$\frac { \sqrt { 2 \cdot 5 } \times 2 \frac { 13 } { 18 } \times 0.25 } { 18 } =$$

Aromātai

$$\frac{49\sqrt{10}}{1296}\approx 0.119561424$$

Ngā Upane Otinga

Whakareatia te 2 ki te 5, ka 10.

$$\frac{0.25\sqrt{10}\times \frac{2\times 18+13}{18}}{18}$$

Whakareatia te 2 ki te 18, ka 36.

$$\frac{0.25\sqrt{10}\times \frac{36+13}{18}}{18}$$

Tāpirihia te 36 ki te 13, ka 49.

$$\frac{0.25\sqrt{10}\times \frac{49}{18}}{18}$$

Me tahuri ki tau ā-ira 0.25 ki te hautau \frac{25}{100}. Whakahekea te hautanga \frac{25}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{\frac{1}{4}\sqrt{10}\times \frac{49}{18}}{18}$$

Me whakarea te \frac{1}{4} ki te \frac{49}{18} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{\frac{1\times 49}{4\times 18}\sqrt{10}}{18}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 49}{4\times 18}.

$$\frac{\frac{49}{72}\sqrt{10}}{18}$$

Whakawehea te \frac{49}{72}\sqrt{10} ki te 18, kia riro ko \frac{49}{1296}\sqrt{10}.

$$\frac{49}{1296}\sqrt{10}$$
