Whakaoti i te 27*5^2*(-4)^2/3^3*125*2^3

$$\frac { 27 \times 5 ^ { 2 } \times ( - 4 ) ^ { 2 } } { 3 ^ { 3 } \times 125 \times 2 ^ { 3 } }$$

Aromātai

$$\frac{2}{5}=0.4$$

Ngā Upane Otinga

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

$$\frac{27\times 25\left(-4\right)^{2}}{3^{3}\times 125\times 2^{3}}$$

Whakareatia te 27 ki te 25, ka 675.

$$\frac{675\left(-4\right)^{2}}{3^{3}\times 125\times 2^{3}}$$

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

$$\frac{675\times 16}{3^{3}\times 125\times 2^{3}}$$

Whakareatia te 675 ki te 16, ka 10800.

$$\frac{10800}{3^{3}\times 125\times 2^{3}}$$

Tātaihia te 3 mā te pū o 3, kia riro ko 27.

$$\frac{10800}{27\times 125\times 2^{3}}$$

Whakareatia te 27 ki te 125, ka 3375.

$$\frac{10800}{3375\times 2^{3}}$$

Tātaihia te 2 mā te pū o 3, kia riro ko 8.

$$\frac{10800}{3375\times 8}$$

Whakareatia te 3375 ki te 8, ka 27000.

$$\frac{10800}{27000}$$

Whakahekea te hautanga \frac{10800}{27000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5400.

$$\frac{2}{5}$$

Tauwehe

$$\frac{2}{5} = 0.4$$
