$$x = ( \frac { 2 } { 8.2 \times 10 ^ { 2 } } ) ^ { - 1 }$$

Whakaoti mō x

$$x=410$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 10 mā te pū o 2, kia riro ko 100.

$$x=\left(\frac{2}{8.2\times 100}\right)^{-1}$$

Whakareatia te 8.2 ki te 100, ka 820.

$$x=\left(\frac{2}{820}\right)^{-1}$$

Whakahekea te hautanga \frac{2}{820} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\left(\frac{1}{410}\right)^{-1}$$

Tātaihia te \frac{1}{410} mā te pū o -1, kia riro ko 410.

$$x=410$$

Tautapa x

$$x≔410$$
