Whakaoti i te 7=2pisqrt{l/y}

$$7 = 2 \pi \sqrt { \frac { l } { y } }$$

Whakaoti mō l

$$l=\frac{49y}{4\pi ^{2}}$$

$$y\neq 0$$

Ngā Upane mō te Whakaoti Whārite Pūtake

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

$$2\pi \sqrt{\frac{l}{y}}=7$$

Whakawehea ngā taha e rua ki te 2\pi .

$$\frac{2\pi \sqrt{\frac{1}{y}l}}{2\pi }=\frac{7}{2\pi }$$

Mā te whakawehe ki te 2\pi ka wetekia te whakareanga ki te 2\pi .

$$\sqrt{\frac{1}{y}l}=\frac{7}{2\pi }$$

Pūruatia ngā taha e rua o te whārite.

$$\frac{1}{y}l=\frac{49}{4\pi ^{2}}$$

Whakawehea ngā taha e rua ki te y^{-1}.

$$\frac{\frac{1}{y}ly}{1}=\frac{49}{4\pi ^{2}\times \frac{1}{y}}$$

Mā te whakawehe ki te y^{-1} ka wetekia te whakareanga ki te y^{-1}.

$$l=\frac{49}{4\pi ^{2}\times \frac{1}{y}}$$

Whakawehe \frac{49}{4\pi ^{2}} ki te y^{-1}.

$$l=\frac{49y}{4\pi ^{2}}$$

Whakaoti mō y

$$y=\frac{4\pi ^{2}l}{49}$$

$$l\neq 0$$
