Whakareatia ngā taha e rua o te whārite ki te 4.

$$-4\sqrt[3]{8}+16\times 4+1=-4\left(-2\right)+4\times 27^{\frac{1}{3}}$$

Tātaitia te \sqrt[3]{8} kia tae ki 2.

$$-4\times 2+16\times 4+1=-4\left(-2\right)+4\times 27^{\frac{1}{3}}$$

Whakareatia te -4 ki te 2, ka -8.

$$-8+16\times 4+1=-4\left(-2\right)+4\times 27^{\frac{1}{3}}$$

Whakareatia te 16 ki te 4, ka 64.

$$-8+64+1=-4\left(-2\right)+4\times 27^{\frac{1}{3}}$$

Tāpirihia te -8 ki te 64, ka 56.

$$56+1=-4\left(-2\right)+4\times 27^{\frac{1}{3}}$$

Tāpirihia te 56 ki te 1, ka 57.

$$57=-4\left(-2\right)+4\times 27^{\frac{1}{3}}$$

Whakareatia te -4 ki te -2, ka 8.

$$57=8+4\times 27^{\frac{1}{3}}$$

Tātaihia te 27 mā te pū o \frac{1}{3}, kia riro ko 3.

$$57=8+4\times 3$$

Whakareatia te 4 ki te 3, ka 12.

$$57=8+12$$

Tāpirihia te 8 ki te 12, ka 20.

$$57=20$$

Whakatauritea te 57 me te 20.
