9mil^{2}ions=3.9\times 10^{5}
Whakareatia te l ki te l, ka l^{2}.
9iml^{2}ions=3.9\times 10^{5}
Whakareatia te 9 ki te i, ka 9i.
-9ml^{2}ons=3.9\times 10^{5}
Whakareatia te 9i ki te i, ka -9.
-9ml^{2}ons=3.9\times 100000
Tātaihia te 10 mā te pū o 5, kia riro ko 100000.
\left(-9nosl^{2}\right)m=390000
He hanga arowhānui tō te whārite.
\frac{\left(-9nosl^{2}\right)m}{-9nosl^{2}}=\frac{390000}{-9nosl^{2}}
Whakawehea ngā taha e rua ki te -9l^{2}ons.
m=\frac{390000}{-9nosl^{2}}
Mā te whakawehe ki te -9l^{2}ons ka wetekia te whakareanga ki te -9l^{2}ons.
m=-\frac{130000}{3nosl^{2}}
Whakawehe 390000 ki te -9l^{2}ons.
