Whakaoti i te left(xdiv53.8right)^2*100=79

$${ \left(x \div 53.8 \right) }^{ 2 } \times 100=79$$

Whakaoti mō x

$$x = \frac{269 \sqrt{79}}{50} \approx 47.818485965$$

$$x = -\frac{269 \sqrt{79}}{50} \approx -47.818485965$$

Ngā Upane mā te Kimi Pūtakerua

Whakawehea ngā taha e rua ki te 100.

$$\left(\frac{x}{53.8}\right)^{2}=\frac{79}{100}$$

Kia whakarewa i te \frac{x}{53.8} ki tētahi taupū, me whakarewa tahi te taurunga me te tauraro ki te taupū kātahi ka whakawehe.

$$\frac{x^{2}}{53.8^{2}}=\frac{79}{100}$$

Tātaihia te 53.8 mā te pū o 2, kia riro ko 2894.44.

$$\frac{x^{2}}{2894.44}=\frac{79}{100}$$

Me whakarea ngā taha e rua ki te 2894.44.

$$x^{2}=\frac{79}{100}\times 2894.44$$

Whakareatia te \frac{79}{100} ki te 2894.44, ka \frac{5716519}{2500}.

$$x^{2}=\frac{5716519}{2500}$$

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

$$x=\frac{269\sqrt{79}}{50} x=-\frac{269\sqrt{79}}{50}$$
