Whakaoti i te [1/5*(-3/12)]^2+[7/5*5/12]

$$[ \frac { 1 } { 5 } \times ( \frac { - 3 } { 12 } ) ] ^ { 2 } + [ \frac { 7 } { 5 } \times \frac { 5 } { 12 } ]$$

Aromātai

$$\frac{703}{1200}\approx 0.585833333$$

Ngā Upane Otinga

Whakahekea te hautanga \frac{-3}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\left(\frac{1}{5}\left(-\frac{1}{4}\right)\right)^{2}+\frac{7}{5}\times \frac{5}{12}$$

Whakareatia te \frac{1}{5} ki te -\frac{1}{4}, ka -\frac{1}{20}.

$$\left(-\frac{1}{20}\right)^{2}+\frac{7}{5}\times \frac{5}{12}$$

Tātaihia te -\frac{1}{20} mā te pū o 2, kia riro ko \frac{1}{400}.

$$\frac{1}{400}+\frac{7}{5}\times \frac{5}{12}$$

Whakareatia te \frac{7}{5} ki te \frac{5}{12}, ka \frac{7}{12}.

$$\frac{1}{400}+\frac{7}{12}$$

Tāpirihia te \frac{1}{400} ki te \frac{7}{12}, ka \frac{703}{1200}.

$$\frac{703}{1200}$$

Tauwehe

$$\frac{19 \cdot 37}{2 ^ {4} \cdot 3 \cdot 5 ^ {2}} = 0.5858333333333333$$
