Whakaoti i te 4*5^2+6*(5div4^2)=

$$4 \cdot 5 ^ { 2 } + 6 \cdot ( 5 \div 4 ^ { 2 } ) =$$

Aromātai

$$\frac{815}{8}=101.875$$

Ngā Upane Otinga

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

$$4\times 25+6\times \frac{5}{4^{2}}$$

Whakareatia te 4 ki te 25, ka 100.

$$100+6\times \frac{5}{4^{2}}$$

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

$$100+6\times \frac{5}{16}$$

Tuhia te 6\times \frac{5}{16} hei hautanga kotahi.

$$100+\frac{6\times 5}{16}$$

Whakareatia te 6 ki te 5, ka 30.

$$100+\frac{30}{16}$$

Whakahekea te hautanga \frac{30}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$100+\frac{15}{8}$$

Me tahuri te 100 ki te hautau \frac{800}{8}.

$$\frac{800}{8}+\frac{15}{8}$$

Tā te mea he rite te tauraro o \frac{800}{8} me \frac{15}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{800+15}{8}$$

Tāpirihia te 800 ki te 15, ka 815.

$$\frac{815}{8}$$

Tauwehe

$$\frac{5 \cdot 163}{2 ^ {3}} = 101\frac{7}{8} = 101.875$$
