Whakaoti i te 218*10^-18quadx=663*10^-34*3*10^8/434*10^-9

$$218 \times 10 ^ { - 18 } \quad x = \frac { 663 \times 10 ^ { - 34 } \times 3 \times 10 ^ { 8 } } { 434 \times 10 ^ { - 9 } }$$

Whakaoti mō x

$$x=\frac{9945}{47306}\approx 0.210227033$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -34 me te 8 kia riro ai te -26.

$$218\times 10^{-18}x=\frac{663\times 10^{-26}\times 3}{434\times 10^{-9}}$$

Tātaihia te 10 mā te pū o -18, kia riro ko \frac{1}{1000000000000000000}.

$$218\times \frac{1}{1000000000000000000}x=\frac{663\times 10^{-26}\times 3}{434\times 10^{-9}}$$

Whakareatia te 218 ki te \frac{1}{1000000000000000000}, ka \frac{109}{500000000000000000}.

$$\frac{109}{500000000000000000}x=\frac{663\times 10^{-26}\times 3}{434\times 10^{-9}}$$

Hei whakawehe i ngā pū o te pūtake kotahi, tangohia te taupū o te taurunga i te taupū o te tauraro.

$$\frac{109}{500000000000000000}x=\frac{3\times 663}{434\times 10^{17}}$$

Whakareatia te 3 ki te 663, ka 1989.

$$\frac{109}{500000000000000000}x=\frac{1989}{434\times 10^{17}}$$

Tātaihia te 10 mā te pū o 17, kia riro ko 100000000000000000.

$$\frac{109}{500000000000000000}x=\frac{1989}{434\times 100000000000000000}$$

Whakareatia te 434 ki te 100000000000000000, ka 43400000000000000000.

$$\frac{109}{500000000000000000}x=\frac{1989}{43400000000000000000}$$

Me whakarea ngā taha e rua ki te \frac{500000000000000000}{109}, te tau utu o \frac{109}{500000000000000000}.

$$x=\frac{1989}{43400000000000000000}\times \frac{500000000000000000}{109}$$

Whakareatia te \frac{1989}{43400000000000000000} ki te \frac{500000000000000000}{109}, ka \frac{9945}{47306}.

$$x=\frac{9945}{47306}$$
