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

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

Aromātai

$$\frac{481}{400}=1.2025$$

Ngā Upane Otinga

Tātaihia te \frac{3}{4} mā te pū o 2, kia riro ko \frac{9}{16}.

$$\frac{9}{16}+\left(\frac{4}{5}\right)^{2}$$

Tātaihia te \frac{4}{5} mā te pū o 2, kia riro ko \frac{16}{25}.

$$\frac{9}{16}+\frac{16}{25}$$

Ko te maha noa iti rawa atu o 16 me 25 ko 400. Me tahuri \frac{9}{16} me \frac{16}{25} ki te hautau me te tautūnga 400.

$$\frac{225}{400}+\frac{256}{400}$$

Tā te mea he rite te tauraro o \frac{225}{400} me \frac{256}{400}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{225+256}{400}$$

Tāpirihia te 225 ki te 256, ka 481.

$$\frac{481}{400}$$

Tauwehe

$$\frac{13 \cdot 37}{2 ^ {4} \cdot 5 ^ {2}} = 1\frac{81}{400} = 1.2025$$
