Whakaoti i te 3/n^2=n-4/3n^2+2/3n^

$$\frac{ 3 }{ { n }^{ 2 } } = \frac{ n-4 }{ 3 { n }^{ 2 } } + \frac{ 2 }{ 3 { n }^{ } }$$

Whakaoti mō n

$$n = \frac{13}{3} = 4\frac{1}{3} \approx 4.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe n ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 3n^{2}, arā, te tauraro pātahi he tino iti rawa te kitea o n^{2},3n^{2},3n^{1}.

$$3\times 3=n-4+n\times 2$$

Whakareatia te 3 ki te 3, ka 9.

$$9=n-4+n\times 2$$

Pahekotia te n me n\times 2, ka 3n.

$$9=3n-4$$

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

$$3n-4=9$$

Me tāpiri te 4 ki ngā taha e rua.

$$3n=9+4$$

Tāpirihia te 9 ki te 4, ka 13.

$$3n=13$$

Whakawehea ngā taha e rua ki te 3.

$$n=\frac{13}{3}$$
