$$6\sqrt{10}-80\approx -61.026334039$$

Ngā Upane Otinga

Tuhia anō te whakawehe o ngā pūtake rua \frac{\sqrt{144}}{\sqrt{0.4}} hei pūtake rua o te whakawehenga \sqrt{\frac{144}{0.4}} ka mahi i te whakawehenga.

$$\sqrt{72}-\sqrt{2.56}\sqrt{2500}$$

Tauwehea te 72=6^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{6^{2}\times 2} hei hua o ngā pūtake rua \sqrt{6^{2}}\sqrt{2}. Tuhia te pūtakerua o te 6^{2}.

$$6\sqrt{2}-\sqrt{2.56}\sqrt{2500}$$

Tātaitia te pūtakerua o 2.56 kia tae ki 1.6.

$$6\sqrt{2}-1.6\sqrt{2500}$$

Tātaitia te pūtakerua o 2500 kia tae ki 50.

$$6\sqrt{2}-1.6\times 50$$

Whakareatia te 1.6 ki te 50, ka 80.

$$6\sqrt{2}-80$$
