Whakaoti i te x^2=505

$$x ^ { 2 } = 505$$

Whakaoti mō x

$$x=\sqrt{505}\approx 22.472205054$$

$$x=-\sqrt{505}\approx -22.472205054$$

Ngā Upane mā te Kimi Pūtakerua

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

$$x=\sqrt{505} x=-\sqrt{505}$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Tangohia te 505 mai i ngā taha e rua.

$$x^{2}-505=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -505 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\left(-505\right)}}{2}$$

Pūrua 0.

$$x=\frac{0±\sqrt{-4\left(-505\right)}}{2}$$

Whakareatia -4 ki te -505.

$$x=\frac{0±\sqrt{2020}}{2}$$

Tuhia te pūtakerua o te 2020.

$$x=\frac{0±2\sqrt{505}}{2}$$

Nā, me whakaoti te whārite x=\frac{0±2\sqrt{505}}{2} ina he tāpiri te ±.

$$x=\sqrt{505}$$

Nā, me whakaoti te whārite x=\frac{0±2\sqrt{505}}{2} ina he tango te ±.

$$x=-\sqrt{505}$$

Kua oti te whārite te whakatau.

$$x=\sqrt{505} x=-\sqrt{505}$$
