Whakaoti i te A=3sqrt{10}-5,quadB=2sqrt{10-2},quadC=3sqrt{3-2}

$$A = 3 \sqrt { 10 } - 5 , \quad B = 2 \sqrt { 10 - 2 } , \quad C = 3 \sqrt { 3 - 2 }$$

Whakaoti mō A, B, C

$$A=3\sqrt{10}-5\approx 4.486832981$$

$$B=4\sqrt{2}\approx 5.656854249$$

$$C=3$$

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Tangohia te 2 i te 10, ka 8.

$$B=2\sqrt{8}$$

Tauwehea te 8=2^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 2} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{2}. Tuhia te pūtakerua o te 2^{2}.

$$B=2\times 2\sqrt{2}$$

Whakareatia te 2 ki te 2, ka 4.

$$B=4\sqrt{2}$$

Whakaarohia te whārite tuatoru. Tangohia te 2 i te 3, ka 1.

$$C=3\sqrt{1}$$

Tātaitia te pūtakerua o 1 kia tae ki 1.

$$C=3\times 1$$

Whakareatia te 3 ki te 1, ka 3.

$$C=3$$

Kua oti te pūnaha te whakatau.

$$A=3\sqrt{10}-5 B=4\sqrt{2} C=3$$
