Whakaoti i te 5*5/2+7*(5sqrt{2})-2

$$\frac { 5 \times 5 } { 2 } + 7 \times ( 5 \sqrt { 2 } ) - 2$$

Aromātai

$$35\sqrt{2}+\frac{21}{2}\approx 59.997474683$$

Ngā Upane Otinga

Whakareatia te 5 ki te 5, ka 25.

$$\frac{25}{2}+7\times 5\sqrt{2}-2$$

Whakareatia te 7 ki te 5, ka 35.

$$\frac{25}{2}+35\sqrt{2}-2$$

Me tahuri te 2 ki te hautau \frac{4}{2}.

$$\frac{25}{2}+35\sqrt{2}-\frac{4}{2}$$

Tā te mea he rite te tauraro o \frac{25}{2} me \frac{4}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{25-4}{2}+35\sqrt{2}$$

Tangohia te 4 i te 25, ka 21.

$$\frac{21}{2}+35\sqrt{2}$$

Tauwehe

$$\frac{7 {(10 \sqrt{2} + 3)}}{2} = 59.99747468305833$$
