Whakaoti i te 4-5*(-1/2)^3

$$4 - 5 \times ( - \frac { 1 } { 2 } ) ^ { 3 }$$

Aromātai

$$\frac{37}{8}=4.625$$

Ngā Upane Otinga

Tātaihia te -\frac{1}{2} mā te pū o 3, kia riro ko -\frac{1}{8}.

$$4-5\left(-\frac{1}{8}\right)$$

Tuhia te 5\left(-\frac{1}{8}\right) hei hautanga kotahi.

$$4-\frac{5\left(-1\right)}{8}$$

Whakareatia te 5 ki te -1, ka -5.

$$4-\frac{-5}{8}$$

Ka taea te hautanga \frac{-5}{8} te tuhi anō ko -\frac{5}{8} mā te tango i te tohu tōraro.

$$4-\left(-\frac{5}{8}\right)$$

Ko te tauaro o -\frac{5}{8} ko \frac{5}{8}.

$$4+\frac{5}{8}$$

Me tahuri te 4 ki te hautau \frac{32}{8}.

$$\frac{32}{8}+\frac{5}{8}$$

Tā te mea he rite te tauraro o \frac{32}{8} me \frac{5}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{32+5}{8}$$

Tāpirihia te 32 ki te 5, ka 37.

$$\frac{37}{8}$$

Tauwehe

$$\frac{37}{2 ^ {3}} = 4\frac{5}{8} = 4.625$$
