Whakaoti i te -24*5^2+3(93-43)^2/2*25*60

$$\frac { - 24 \times 5 ^ { 2 } + 3 ( 93 - 43 ) ^ { 2 } } { 2 \times 25 \times 60 }$$

Aromātai

$$\frac{23}{10}=2.3$$

Ngā Upane Otinga

Tātaihia te 5 mā te pū o 2, kia riro ko 25.

$$\frac{-24\times 25+3\left(93-43\right)^{2}}{2\times 25\times 60}$$

Whakareatia te -24 ki te 25, ka -600.

$$\frac{-600+3\left(93-43\right)^{2}}{2\times 25\times 60}$$

Tangohia te 43 i te 93, ka 50.

$$\frac{-600+3\times 50^{2}}{2\times 25\times 60}$$

Tātaihia te 50 mā te pū o 2, kia riro ko 2500.

$$\frac{-600+3\times 2500}{2\times 25\times 60}$$

Whakareatia te 3 ki te 2500, ka 7500.

$$\frac{-600+7500}{2\times 25\times 60}$$

Tāpirihia te -600 ki te 7500, ka 6900.

$$\frac{6900}{2\times 25\times 60}$$

Whakareatia te 2 ki te 25, ka 50.

$$\frac{6900}{50\times 60}$$

Whakareatia te 50 ki te 60, ka 3000.

$$\frac{6900}{3000}$$

Whakahekea te hautanga \frac{6900}{3000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 300.

$$\frac{23}{10}$$

Tauwehe

$$\frac{23}{2 \cdot 5} = 2\frac{3}{10} = 2.3$$
