Whakaoti i te 72-(85^2*720^3)div(-820)+22=x

$$72 - ( 85 ^ { 2 } \times 720 ^ { 3 } ) \div ( - 820 ) + 22 = x$$

Whakaoti mō x

$$x = \frac{134835843854}{41} = 3288679118\frac{16}{41} \approx 3288679118.390243902$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 85 mā te pū o 2, kia riro ko 7225.

$$72-\frac{7225\times 720^{3}}{-820}+22=x$$

Tātaihia te 720 mā te pū o 3, kia riro ko 373248000.

$$72-\frac{7225\times 373248000}{-820}+22=x$$

Whakareatia te 7225 ki te 373248000, ka 2696716800000.

$$72-\frac{2696716800000}{-820}+22=x$$

Whakahekea te hautanga \frac{2696716800000}{-820} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.

$$72-\left(-\frac{134835840000}{41}\right)+22=x$$

Ko te tauaro o -\frac{134835840000}{41} ko \frac{134835840000}{41}.

$$72+\frac{134835840000}{41}+22=x$$

Me tahuri te 72 ki te hautau \frac{2952}{41}.

$$\frac{2952}{41}+\frac{134835840000}{41}+22=x$$

Tā te mea he rite te tauraro o \frac{2952}{41} me \frac{134835840000}{41}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2952+134835840000}{41}+22=x$$

Tāpirihia te 2952 ki te 134835840000, ka 134835842952.

$$\frac{134835842952}{41}+22=x$$

Me tahuri te 22 ki te hautau \frac{902}{41}.

$$\frac{134835842952}{41}+\frac{902}{41}=x$$

Tā te mea he rite te tauraro o \frac{134835842952}{41} me \frac{902}{41}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{134835842952+902}{41}=x$$

Tāpirihia te 134835842952 ki te 902, ka 134835843854.

$$\frac{134835843854}{41}=x$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$x=\frac{134835843854}{41}$$
