$$\frac{28\sqrt{59605}}{655}\approx 10.436576901$$

Ngā Upane Otinga

Tuhia te 52\times \frac{28}{655} hei hautanga kotahi.

$$7\sqrt{\frac{52\times 28}{655}}$$

Whakareatia te 52 ki te 28, ka 1456.

$$7\sqrt{\frac{1456}{655}}$$

Tuhia anō te pūtake rua o te whakawehenga \sqrt{\frac{1456}{655}} hei whakawehenga o ngā pūtake rua \frac{\sqrt{1456}}{\sqrt{655}}.

$$7\times \frac{\sqrt{1456}}{\sqrt{655}}$$

Tauwehea te 1456=4^{2}\times 91. Tuhia anō te pūtake rua o te hua \sqrt{4^{2}\times 91} hei hua o ngā pūtake rua \sqrt{4^{2}}\sqrt{91}. Tuhia te pūtakerua o te 4^{2}.

$$7\times \frac{4\sqrt{91}}{\sqrt{655}}$$

Whakangāwaritia te tauraro o \frac{4\sqrt{91}}{\sqrt{655}} mā te whakarea i te taurunga me te tauraro ki te \sqrt{655}.

$$7\times \frac{4\sqrt{91}\sqrt{655}}{\left(\sqrt{655}\right)^{2}}$$

Ko te pūrua o \sqrt{655} ko 655.

$$7\times \frac{4\sqrt{91}\sqrt{655}}{655}$$

Hei whakarea \sqrt{91} me \sqrt{655}, whakareatia ngā tau i raro i te pūtake rua.

$$7\times \frac{4\sqrt{59605}}{655}$$

Tuhia te 7\times \frac{4\sqrt{59605}}{655} hei hautanga kotahi.

$$\frac{7\times 4\sqrt{59605}}{655}$$

Whakareatia te 7 ki te 4, ka 28.
