Whakaoti i te (4^2/5)*(4^-3/5)+(2^2/5^2)

$$( \frac{ { 4 }^{ 2 } }{ 5 } ) \times ( \frac{ { 4 }^{ -3 } }{ 5 } )+( \frac{ { 2 }^{ 2 } }{ { 5 }^{ 2 } } )$$

Aromātai

$$\frac{17}{100}=0.17$$

Ngā Upane Otinga

Tātaihia te 4 mā te pū o 2, kia riro ko 16.

$$\frac{16}{5}\times \frac{4^{-3}}{5}+\frac{2^{2}}{5^{2}}$$

Tātaihia te 4 mā te pū o -3, kia riro ko \frac{1}{64}.

$$\frac{16}{5}\times \frac{\frac{1}{64}}{5}+\frac{2^{2}}{5^{2}}$$

Tuhia te \frac{\frac{1}{64}}{5} hei hautanga kotahi.

$$\frac{16}{5}\times \frac{1}{64\times 5}+\frac{2^{2}}{5^{2}}$$

Whakareatia te 64 ki te 5, ka 320.

$$\frac{16}{5}\times \frac{1}{320}+\frac{2^{2}}{5^{2}}$$

Whakareatia te \frac{16}{5} ki te \frac{1}{320}, ka \frac{1}{100}.

$$\frac{1}{100}+\frac{2^{2}}{5^{2}}$$

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

$$\frac{1}{100}+\frac{4}{5^{2}}$$

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

$$\frac{1}{100}+\frac{4}{25}$$

Tāpirihia te \frac{1}{100} ki te \frac{4}{25}, ka \frac{17}{100}.

$$\frac{17}{100}$$

Tauwehe

$$\frac{17}{2 ^ {2} \cdot 5 ^ {2}} = 0.17$$
