9^{2}\left(\sqrt{x}\right)^{2}-43x=76
Whakarohaina te \left(9\sqrt{x}\right)^{2}.
81\left(\sqrt{x}\right)^{2}-43x=76
Tātaihia te 9 mā te pū o 2, kia riro ko 81.
81x-43x=76
Tātaihia te \sqrt{x} mā te pū o 2, kia riro ko x.
38x=76
Pahekotia te 81x me -43x, ka 38x.
x=\frac{76}{38}
Whakawehea ngā taha e rua ki te 38.
x=2
Whakawehea te 76 ki te 38, kia riro ko 2.
