Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -5 me te -5 kia riro ai te -10.

$$\frac{4\times 10^{-10}\times 4}{0.79^{2}}\times \frac{9\times 10^{9}}{2.2}$$

Tātaihia te 10 mā te pū o -10, kia riro ko \frac{1}{10000000000}.

$$\frac{4\times \frac{1}{10000000000}\times 4}{0.79^{2}}\times \frac{9\times 10^{9}}{2.2}$$

Whakareatia te 4 ki te \frac{1}{10000000000}, ka \frac{1}{2500000000}.

$$\frac{\frac{1}{2500000000}\times 4}{0.79^{2}}\times \frac{9\times 10^{9}}{2.2}$$

Whakareatia te \frac{1}{2500000000} ki te 4, ka \frac{1}{625000000}.

$$\frac{\frac{1}{625000000}}{0.79^{2}}\times \frac{9\times 10^{9}}{2.2}$$

Tātaihia te 0.79 mā te pū o 2, kia riro ko 0.6241.

$$\frac{\frac{1}{625000000}}{0.6241}\times \frac{9\times 10^{9}}{2.2}$$

Tuhia te \frac{\frac{1}{625000000}}{0.6241} hei hautanga kotahi.

$$\frac{1}{625000000\times 0.6241}\times \frac{9\times 10^{9}}{2.2}$$

Whakareatia te 625000000 ki te 0.6241, ka 390062500.

$$\frac{1}{390062500}\times \frac{9\times 10^{9}}{2.2}$$

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

$$\frac{1}{390062500}\times \frac{9\times 1000000000}{2.2}$$

Whakareatia te 9 ki te 1000000000, ka 9000000000.

$$\frac{1}{390062500}\times \frac{9000000000}{2.2}$$

Whakarohaina te \frac{9000000000}{2.2} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{1}{390062500}\times \frac{90000000000}{22}$$

Whakahekea te hautanga \frac{90000000000}{22} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1}{390062500}\times \frac{45000000000}{11}$$

Whakareatia te \frac{1}{390062500} ki te \frac{45000000000}{11}, ka \frac{720000}{68651}.

$$\frac{720000}{68651}$$

Tauwehe

$$\frac{2 ^ {7} \cdot 3 ^ {2} \cdot 5 ^ {4}}{11 \cdot 79 ^ {2}} = 10\frac{33490}{68651} = 10.487829747563765$$
