Whakaoti i te sqrt{(0.8)(0.1)^2/9*10^9}

$$\sqrt { \frac { ( 0.8 ) ( 0.1 ) ^ { 2 } } { 9 \times 10 ^ { 9 } } }$$

Aromātai

$$\frac{\sqrt{2}}{1500000}\approx 0.000000943$$

Ngā Upane Otinga

Tātaihia te 0.1 mā te pū o 2, kia riro ko 0.01.

$$\sqrt{\frac{0.8\times 0.01}{9\times 10^{9}}}$$

Whakareatia te 0.8 ki te 0.01, ka 0.008.

$$\sqrt{\frac{0.008}{9\times 10^{9}}}$$

Tātaihia te 10 mā te pū o 9, kia riro ko 1000000000.

$$\sqrt{\frac{0.008}{9\times 1000000000}}$$

Whakareatia te 9 ki te 1000000000, ka 9000000000.

$$\sqrt{\frac{0.008}{9000000000}}$$

Whakarohaina te \frac{0.008}{9000000000} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$\sqrt{\frac{8}{9000000000000}}$$

Whakahekea te hautanga \frac{8}{9000000000000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.

$$\sqrt{\frac{1}{1125000000000}}$$

Tuhia anō te pūtake rua o te whakawehenga \sqrt{\frac{1}{1125000000000}} hei whakawehenga o ngā pūtake rua \frac{\sqrt{1}}{\sqrt{1125000000000}}.

$$\frac{\sqrt{1}}{\sqrt{1125000000000}}$$

Tātaitia te pūtakerua o 1 kia tae ki 1.

$$\frac{1}{\sqrt{1125000000000}}$$

Tauwehea te 1125000000000=750000^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{750000^{2}\times 2} hei hua o ngā pūtake rua \sqrt{750000^{2}}\sqrt{2}. Tuhia te pūtakerua o te 750000^{2}.

$$\frac{1}{750000\sqrt{2}}$$

Whakangāwaritia te tauraro o \frac{1}{750000\sqrt{2}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{2}.

$$\frac{\sqrt{2}}{750000\left(\sqrt{2}\right)^{2}}$$

Ko te pūrua o \sqrt{2} ko 2.

$$\frac{\sqrt{2}}{750000\times 2}$$

Whakareatia te 750000 ki te 2, ka 1500000.

$$\frac{\sqrt{2}}{1500000}$$
