Whakaoti i te f_{3}(u)=0.72*sqrt{200}+0.08*sqrt{110}+0.18*sqrt{190}+0.02*sqrt{100}

$$f _ { 3 } ( u ) = 0.72 \times \sqrt { 200 } + 0.08 \times \sqrt { 110 } + 0.18 \times \sqrt { 190 } + 0.02 \times \sqrt { 100 }$$

Aromātai

$$\frac{2\sqrt{110}}{25}+\frac{9\sqrt{190}}{50}+\frac{36\sqrt{2}}{5}+0.2\approx 13.702513503$$

Ngā Upane Otinga

Tauwehea te 200=10^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{10^{2}\times 2} hei hua o ngā pūtake rua \sqrt{10^{2}}\sqrt{2}. Tuhia te pūtakerua o te 10^{2}.

$$0.72\times 10\sqrt{2}+0.08\sqrt{110}+0.18\sqrt{190}+0.02\sqrt{100}$$

Whakareatia te 0.72 ki te 10, ka 7.2.

$$7.2\sqrt{2}+0.08\sqrt{110}+0.18\sqrt{190}+0.02\sqrt{100}$$

Tātaitia te pūtakerua o 100 kia tae ki 10.

$$7.2\sqrt{2}+0.08\sqrt{110}+0.18\sqrt{190}+0.02\times 10$$

Whakareatia te 0.02 ki te 10, ka 0.2.

$$7.2\sqrt{2}+0.08\sqrt{110}+0.18\sqrt{190}+0.2$$
