$$\sqrt { \frac { 0.083 ( 1 - 0.083 ) } { 80 } }$$

Aromātai

$$\frac{\sqrt{380555}}{20000}\approx 0.03084457$$

Ngā Upane Otinga

Tangohia te 0.083 i te 1, ka 0.917.

$$\sqrt{\frac{0.083\times 0.917}{80}}$$

Whakareatia te 0.083 ki te 0.917, ka 0.076111.

$$\sqrt{\frac{0.076111}{80}}$$

Whakarohaina te \frac{0.076111}{80} mā te whakarea i te taurunga me te tauraro ki te 1000000.

$$\sqrt{\frac{76111}{80000000}}$$

Tuhia anō te pūtake rua o te whakawehenga \sqrt{\frac{76111}{80000000}} hei whakawehenga o ngā pūtake rua \frac{\sqrt{76111}}{\sqrt{80000000}}.

$$\frac{\sqrt{76111}}{\sqrt{80000000}}$$

Tauwehea te 80000000=4000^{2}\times 5. Tuhia anō te pūtake rua o te hua \sqrt{4000^{2}\times 5} hei hua o ngā pūtake rua \sqrt{4000^{2}}\sqrt{5}. Tuhia te pūtakerua o te 4000^{2}.

$$\frac{\sqrt{76111}}{4000\sqrt{5}}$$

Whakangāwaritia te tauraro o \frac{\sqrt{76111}}{4000\sqrt{5}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{5}.

$$\frac{\sqrt{76111}\sqrt{5}}{4000\left(\sqrt{5}\right)^{2}}$$

Ko te pūrua o \sqrt{5} ko 5.

$$\frac{\sqrt{76111}\sqrt{5}}{4000\times 5}$$

Hei whakarea \sqrt{76111} me \sqrt{5}, whakareatia ngā tau i raro i te pūtake rua.

$$\frac{\sqrt{380555}}{4000\times 5}$$

Whakareatia te 4000 ki te 5, ka 20000.

$$\frac{\sqrt{380555}}{20000}$$
