Whakaoti i te 0*2+1/2*7.35*2^2

$$0 \times 2+ \frac{ 1 }{ 2 } \times 7.35 \times { 2 }^{ 2 }$$

Aromātai

$$14.7$$

Ngā Upane Otinga

Whakareatia te 0 ki te 2, ka 0.

$$0+\frac{1}{2}\times 7.35\times 2^{2}$$

Me tahuri ki tau ā-ira 7.35 ki te hautau \frac{735}{100}. Whakahekea te hautanga \frac{735}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$0+\frac{1}{2}\times \frac{147}{20}\times 2^{2}$$

Me whakarea te \frac{1}{2} ki te \frac{147}{20} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$0+\frac{1\times 147}{2\times 20}\times 2^{2}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 147}{2\times 20}.

$$0+\frac{147}{40}\times 2^{2}$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$0+\frac{147}{40}\times 4$$

Tuhia te \frac{147}{40}\times 4 hei hautanga kotahi.

$$0+\frac{147\times 4}{40}$$

Whakareatia te 147 ki te 4, ka 588.

$$0+\frac{588}{40}$$

Whakahekea te hautanga \frac{588}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$0+\frac{147}{10}$$

Tāpirihia te 0 ki te \frac{147}{10}, ka \frac{147}{10}.

$$\frac{147}{10}$$

Tauwehe

$$\frac{3 \cdot 7 ^ {2}}{2 \cdot 5} = 14\frac{7}{10} = 14.7$$
