Whakaoti i te (+5+7-4)=+8ab^4

$$( + 5 + 7 - 4 ) = + 8 a b ^ { 4 }$$

Whakaoti mō a

$$a=\frac{1}{b^{4}}$$

$$b\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tāpirihia te 5 ki te 7, ka 12.

$$12-4=8ab^{4}$$

Tangohia te 4 i te 12, ka 8.

$$8=8ab^{4}$$

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

$$8ab^{4}=8$$

He hanga arowhānui tō te whārite.

$$8b^{4}a=8$$

Whakawehea ngā taha e rua ki te 8b^{4}.

$$\frac{8b^{4}a}{8b^{4}}=\frac{8}{8b^{4}}$$

Mā te whakawehe ki te 8b^{4} ka wetekia te whakareanga ki te 8b^{4}.

$$a=\frac{8}{8b^{4}}$$

Whakawehe 8 ki te 8b^{4}.

$$a=\frac{1}{b^{4}}$$

Whakaoti mō b

$$b=\frac{1}{\sqrt[4]{a}}$$

$$b=-\frac{1}{\sqrt[4]{a}}\text{, }a>0$$
