Me whakakore tahi te 2\times 40 i te taurunga me te tauraro.

$$\frac{\left(6\times 30-10\times 34\right)^{2}}{16\times 20\times 64}=125$$

Whakareatia te 6 ki te 30, ka 180.

$$\frac{\left(180-10\times 34\right)^{2}}{16\times 20\times 64}=125$$

Whakareatia te 10 ki te 34, ka 340.

$$\frac{\left(180-340\right)^{2}}{16\times 20\times 64}=125$$

Tangohia te 340 i te 180, ka -160.

$$\frac{\left(-160\right)^{2}}{16\times 20\times 64}=125$$

Tātaihia te -160 mā te pū o 2, kia riro ko 25600.

$$\frac{25600}{16\times 20\times 64}=125$$

Whakareatia te 16 ki te 20, ka 320.

$$\frac{25600}{320\times 64}=125$$

Whakareatia te 320 ki te 64, ka 20480.

$$\frac{25600}{20480}=125$$

Whakahekea te hautanga \frac{25600}{20480} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5120.

$$\frac{5}{4}=125$$

Me tahuri te 125 ki te hautau \frac{500}{4}.

$$\frac{5}{4}=\frac{500}{4}$$

Whakatauritea te \frac{5}{4} me te \frac{500}{4}.
