Whakareatia ngā taha e rua o te whārite ki te 28.

$$\frac{14336}{5}\times 2^{-1}\times 4\times 3\times 15=4^{3}$$

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

$$\frac{14336}{5}\times \frac{1}{2}\times 4\times 3\times 15=4^{3}$$

Whakareatia te \frac{14336}{5} ki te \frac{1}{2}, ka \frac{7168}{5}.

$$\frac{7168}{5}\times 4\times 3\times 15=4^{3}$$

Whakareatia te \frac{7168}{5} ki te 4, ka \frac{28672}{5}.

$$\frac{28672}{5}\times 3\times 15=4^{3}$$

Whakareatia te \frac{28672}{5} ki te 3, ka \frac{86016}{5}.

$$\frac{86016}{5}\times 15=4^{3}$$

Whakareatia te \frac{86016}{5} ki te 15, ka 258048.

$$258048=4^{3}$$

Tātaihia te 4 mā te pū o 3, kia riro ko 64.

$$258048=64$$

Whakatauritea te 258048 me te 64.
