Whakaoti i te 1/8x314x100-1/4*314*25-1/2*5*5

$$\frac { 1 } { 8 } x 314 x 100 - \frac { 1 } { 4 } \times 314 \times 25 - \frac { 1 } { 2 } \times 5 \times 5$$

Aromātai

$$\frac{x_{100}x_{314}}{8}-1975$$

Ngā Upane Otinga

Whakareatia te \frac{1}{4} ki te 314, ka \frac{314}{4}.

$$\frac{1}{8}x_{314}x_{100}-\frac{314}{4}\times 25-\frac{1}{2}\times 5\times 5$$

Whakahekea te hautanga \frac{314}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{1}{8}x_{314}x_{100}-\frac{157}{2}\times 25-\frac{1}{2}\times 5\times 5$$

Tuhia te \frac{157}{2}\times 25 hei hautanga kotahi.

$$\frac{1}{8}x_{314}x_{100}-\frac{157\times 25}{2}-\frac{1}{2}\times 5\times 5$$

Whakareatia te 157 ki te 25, ka 3925.

$$\frac{1}{8}x_{314}x_{100}-\frac{3925}{2}-\frac{1}{2}\times 5\times 5$$

Whakareatia te \frac{1}{2} ki te 5, ka \frac{5}{2}.

$$\frac{1}{8}x_{314}x_{100}-\frac{3925}{2}-\frac{5}{2}\times 5$$

Tuhia te \frac{5}{2}\times 5 hei hautanga kotahi.

$$\frac{1}{8}x_{314}x_{100}-\frac{3925}{2}-\frac{5\times 5}{2}$$

Whakareatia te 5 ki te 5, ka 25.

$$\frac{1}{8}x_{314}x_{100}-\frac{3925}{2}-\frac{25}{2}$$

Tā te mea he rite te tauraro o -\frac{3925}{2} me \frac{25}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1}{8}x_{314}x_{100}+\frac{-3925-25}{2}$$

Tangohia te 25 i te -3925, ka -3950.

$$\frac{1}{8}x_{314}x_{100}+\frac{-3950}{2}$$

Whakawehea te -3950 ki te 2, kia riro ko -1975.

$$\frac{1}{8}x_{314}x_{100}-1975$$

Tauwehe

$$\frac{x_{100}x_{314}-15800}{8}$$

Ngā Upane Otinga

Tauwehea te \frac{1}{8}.

$$\frac{x_{314}x_{100}-15800}{8}$$
