Whakaoti i te [2/3div(-4)-1/4*(-04)]div(1/3)^2-(-2)

$$[ \frac { 2 } { 3 } \div ( - 4 ) - \frac { 1 } { 4 } \times ( - 04 ) ] \div ( \frac { 1 } { 3 } ) ^ { 2 } - ( - 2 )$$

Aromātai

$$\frac{1}{2}=0.5$$

Ngā Upane Otinga

Tuhia te \frac{\frac{2}{3}}{-4} hei hautanga kotahi.

$$\frac{\frac{2}{3\left(-4\right)}-\frac{1}{4}\times 0\times 4}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

Whakareatia te 3 ki te -4, ka -12.

$$\frac{\frac{2}{-12}-\frac{1}{4}\times 0\times 4}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

Whakahekea te hautanga \frac{2}{-12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{-\frac{1}{6}-\frac{1}{4}\times 0\times 4}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

Whakareatia te \frac{1}{4} ki te 0, ka 0.

$$\frac{-\frac{1}{6}-0\times 4}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

Whakareatia te 0 ki te 4, ka 0.

$$\frac{-\frac{1}{6}-0}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

Tangohia te 0 i te -\frac{1}{6}, ka -\frac{1}{6}.

$$\frac{-\frac{1}{6}}{\left(\frac{1}{3}\right)^{2}}-\left(-2\right)$$

Tātaihia te \frac{1}{3} mā te pū o 2, kia riro ko \frac{1}{9}.

$$\frac{-\frac{1}{6}}{\frac{1}{9}}-\left(-2\right)$$

Whakawehe -\frac{1}{6} ki te \frac{1}{9} mā te whakarea -\frac{1}{6} ki te tau huripoki o \frac{1}{9}.

$$-\frac{1}{6}\times 9-\left(-2\right)$$

Tuhia te -\frac{1}{6}\times 9 hei hautanga kotahi.

$$\frac{-9}{6}-\left(-2\right)$$

Whakahekea te hautanga \frac{-9}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{3}{2}-\left(-2\right)$$

Ko te tauaro o -2 ko 2.

$$-\frac{3}{2}+2$$

Me tahuri te 2 ki te hautau \frac{4}{2}.

$$-\frac{3}{2}+\frac{4}{2}$$

Tā te mea he rite te tauraro o -\frac{3}{2} me \frac{4}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-3+4}{2}$$

Tāpirihia te -3 ki te 4, ka 1.

$$\frac{1}{2}$$

Tauwehe

$$\frac{1}{2} = 0.5$$
