Whakaoti i te A=120*10^-2*700*10^9/1.4*(10^4)^4

$$A = \frac { 120 \times 10 ^ { - 2 } \times 700 \times 10 ^ { 9 } } { 1.4 \times ( 10 ^ { 4 } ) ^ { 4 } }$$

Whakaoti mō A

$$A=0.00006$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -2 me te 9 kia riro ai te 7.

$$A=\frac{120\times 10^{7}\times 700}{1.4\times \left(10^{4}\right)^{4}}$$

Hei hiki pū ki tētahi pū anō, me whakarea ngā taupū. Me whakarea te 4 me te 4 kia riro ai te 16.

$$A=\frac{120\times 10^{7}\times 700}{1.4\times 10^{16}}$$

Me whakakore tahi te 10^{7} i te taurunga me te tauraro.

$$A=\frac{120\times 700}{1.4\times 10^{9}}$$

Whakareatia te 120 ki te 700, ka 84000.

$$A=\frac{84000}{1.4\times 10^{9}}$$

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

$$A=\frac{84000}{1.4\times 1000000000}$$

Whakareatia te 1.4 ki te 1000000000, ka 1400000000.

$$A=\frac{84000}{1400000000}$$

Whakahekea te hautanga \frac{84000}{1400000000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 28000.

$$A=\frac{3}{50000}$$

Tautapa A

$$A≔0.00006$$
