$$\frac { ( \frac { 1 } { 50 } ) ^ { 2 } ( 36 ) - 3 \times 1495 + 2 \times 117 } { 75 }$$

Aromātai

$$-\frac{885622}{15625}=-56.679808$$

Ngā Upane Otinga

Tātaihia te \frac{1}{50} mā te pū o 2, kia riro ko \frac{1}{2500}.

$$\frac{\frac{1}{2500}\times 36-3\times 1495+2\times 117}{75}$$

Whakareatia te \frac{1}{2500} ki te 36, ka \frac{36}{2500}.

$$\frac{\frac{36}{2500}-3\times 1495+2\times 117}{75}$$

Whakahekea te hautanga \frac{36}{2500} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{\frac{9}{625}-3\times 1495+2\times 117}{75}$$

Whakareatia te 3 ki te 1495, ka 4485.

$$\frac{\frac{9}{625}-4485+2\times 117}{75}$$

Me tahuri te 4485 ki te hautau \frac{2803125}{625}.

$$\frac{\frac{9}{625}-\frac{2803125}{625}+2\times 117}{75}$$

Tā te mea he rite te tauraro o \frac{9}{625} me \frac{2803125}{625}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{\frac{9-2803125}{625}+2\times 117}{75}$$

Tangohia te 2803125 i te 9, ka -2803116.

$$\frac{-\frac{2803116}{625}+2\times 117}{75}$$

Whakareatia te 2 ki te 117, ka 234.

$$\frac{-\frac{2803116}{625}+234}{75}$$

Me tahuri te 234 ki te hautau \frac{146250}{625}.

$$\frac{-\frac{2803116}{625}+\frac{146250}{625}}{75}$$

Tā te mea he rite te tauraro o -\frac{2803116}{625} me \frac{146250}{625}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\frac{-2803116+146250}{625}}{75}$$

Tāpirihia te -2803116 ki te 146250, ka -2656866.

$$\frac{-\frac{2656866}{625}}{75}$$

Tuhia te \frac{-\frac{2656866}{625}}{75} hei hautanga kotahi.

$$\frac{-2656866}{625\times 75}$$

Whakareatia te 625 ki te 75, ka 46875.

$$\frac{-2656866}{46875}$$

Whakahekea te hautanga \frac{-2656866}{46875} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{885622}{15625}$$

Tauwehe

$$-\frac{885622}{15625} = -56\frac{10622}{15625} = -56.679808$$
