Aromātai

$$\frac{541441}{72900}\approx 7.427174211$$

Ngā Upane Otinga

Tātaihia te 2.7 mā te pū o 2, kia riro ko 7.29.

$$7.29+\frac{1}{2.7^{2}}$$

Tātaihia te 2.7 mā te pū o 2, kia riro ko 7.29.

$$7.29+\frac{1}{7.29}$$

Whakarohaina te \frac{1}{7.29} mā te whakarea i te taurunga me te tauraro ki te 100.

$$7.29+\frac{100}{729}$$

Me tahuri ki tau ā-ira 7.29 ki te hautau \frac{729}{100}.

$$\frac{729}{100}+\frac{100}{729}$$

Ko te maha noa iti rawa atu o 100 me 729 ko 72900. Me tahuri \frac{729}{100} me \frac{100}{729} ki te hautau me te tautūnga 72900.

$$\frac{531441}{72900}+\frac{10000}{72900}$$

Tā te mea he rite te tauraro o \frac{531441}{72900} me \frac{10000}{72900}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{531441+10000}{72900}$$

Tāpirihia te 531441 ki te 10000, ka 541441.

$$\frac{541441}{72900}$$

Tauwehe

$$\frac{73 \cdot 7417}{2 ^ {2} \cdot 3 ^ {6} \cdot 5 ^ {2}} = 7\frac{31141}{72900} = 7.4271742112482855$$
