Whakaoti i te 3^2(5+1.2)-5.8/(frac{1{2}+5^2)div(3+2.1)}

$$\frac{ { 3 }^{ 2 } (5+1.2)-5.8 }{ ( \frac{ 1 }{ 2 } + { 5 }^{ 2 } ) \div (3+2.1) }$$

Aromātai

Ngā Upane Otinga

Tātaihia te 3 mā te pū o 2, kia riro ko 9.

$$\frac{9\left(5+1.2\right)-5.8}{\frac{\frac{1}{2}+5^{2}}{3+2.1}}$$

Tāpirihia te 5 ki te 1.2, ka 6.2.

$$\frac{9\times 6.2-5.8}{\frac{\frac{1}{2}+5^{2}}{3+2.1}}$$

Whakareatia te 9 ki te 6.2, ka 55.8.

$$\frac{55.8-5.8}{\frac{\frac{1}{2}+5^{2}}{3+2.1}}$$

Tangohia te 5.8 i te 55.8, ka 50.

$$\frac{50}{\frac{\frac{1}{2}+5^{2}}{3+2.1}}$$

Tātaihia te 5 mā te pū o 2, kia riro ko 25.

$$\frac{50}{\frac{\frac{1}{2}+25}{3+2.1}}$$

Me tahuri te 25 ki te hautau \frac{50}{2}.

$$\frac{50}{\frac{\frac{1}{2}+\frac{50}{2}}{3+2.1}}$$

Tā te mea he rite te tauraro o \frac{1}{2} me \frac{50}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{50}{\frac{\frac{1+50}{2}}{3+2.1}}$$

Tāpirihia te 1 ki te 50, ka 51.

$$\frac{50}{\frac{\frac{51}{2}}{3+2.1}}$$

Tāpirihia te 3 ki te 2.1, ka 5.1.

$$\frac{50}{\frac{\frac{51}{2}}{5.1}}$$

Tuhia te \frac{\frac{51}{2}}{5.1} hei hautanga kotahi.

$$\frac{50}{\frac{51}{2\times 5.1}}$$

Whakareatia te 2 ki te 5.1, ka 10.2.

$$\frac{50}{\frac{51}{10.2}}$$

Whakarohaina te \frac{51}{10.2} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{50}{\frac{510}{102}}$$

Whakawehea te 510 ki te 102, kia riro ko 5.

$$\frac{50}{5}$$

Whakawehea te 50 ki te 5, kia riro ko 10.

$$10$$
