Whakaoti i te pix^2=22*7

$$\pi { x }^{ 2 } =22 \times 7$$

Whakaoti mō x

$$x=\sqrt{\frac{154}{\pi }}\approx 7.001408606$$

$$x=-\sqrt{\frac{154}{\pi }}\approx -7.001408606$$

Ngā Upane mā te Kimi Pūtakerua

Whakareatia te 22 ki te 7, ka 154.

$$\pi x^{2}=154$$

Whakawehea ngā taha e rua ki te \pi .

$$\frac{\pi x^{2}}{\pi }=\frac{154}{\pi }$$

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

$$x^{2}=\frac{154}{\pi }$$

Tuhia te pūtakerua o ngā taha e rua o te whārite.

$$x=\frac{154}{\sqrt{154\pi }} x=-\frac{154}{\sqrt{154\pi }}$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Whakareatia te 22 ki te 7, ka 154.

$$\pi x^{2}=154$$

Tangohia te 154 mai i ngā taha e rua.

$$\pi x^{2}-154=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi \pi mō a, 0 mō b, me -154 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\pi \left(-154\right)}}{2\pi }$$

Pūrua 0.

$$x=\frac{0±\sqrt{-4\pi \left(-154\right)}}{2\pi }$$

Whakareatia -4 ki te \pi .

$$x=\frac{0±\sqrt{\left(-4\pi \right)\left(-154\right)}}{2\pi }$$

Whakareatia -4\pi ki te -154.

$$x=\frac{0±\sqrt{616\pi }}{2\pi }$$

Tuhia te pūtakerua o te 616\pi .

$$x=\frac{0±2\sqrt{154\pi }}{2\pi }$$

Nā, me whakaoti te whārite x=\frac{0±2\sqrt{154\pi }}{2\pi } ina he tāpiri te ±.

$$x=\frac{154}{\sqrt{154\pi }}$$

Nā, me whakaoti te whārite x=\frac{0±2\sqrt{154\pi }}{2\pi } ina he tango te ±.

$$x=-\frac{154}{\sqrt{154\pi }}$$

Kua oti te whārite te whakatau.

$$x=\frac{154}{\sqrt{154\pi }} x=-\frac{154}{\sqrt{154\pi }}$$
