Kua tāruatia ki te papatopenga
\left(3x\right)^{2}=\left(\sqrt{x}\right)^{2}
Pūruatia ngā taha e rua o te whārite.
3^{2}x^{2}=\left(\sqrt{x}\right)^{2}
Whakarohaina te \left(3x\right)^{2}.
9x^{2}=\left(\sqrt{x}\right)^{2}
Tātaihia te 3 mā te pū o 2, kia riro ko 9.
9x^{2}=x
Tātaihia te \sqrt{x} mā te pū o 2, kia riro ko x.
9x^{2}-x=0
Tangohia te x mai i ngā taha e rua.
x\left(9x-1\right)=0
Tauwehea te x.
x=0 x=\frac{1}{9}
Hei kimi otinga whārite, me whakaoti te x=0 me te 9x-1=0.
3\times 0=\sqrt{0}
Whakakapia te 0 mō te x i te whārite 3x=\sqrt{x}.
0=0
Whakarūnātia. Ko te uara x=0 kua ngata te whārite.
3\times \frac{1}{9}=\sqrt{\frac{1}{9}}
Whakakapia te \frac{1}{9} mō te x i te whārite 3x=\sqrt{x}.
\frac{1}{3}=\frac{1}{3}
Whakarūnātia. Ko te uara x=\frac{1}{9} kua ngata te whārite.
x=0 x=\frac{1}{9}
Rārangihia ngā rongoā katoa o 3x=\sqrt{x}.
