90 = 9 \sqrt { 25 x }
Tohaina
Kua tāruatia ki te papatopenga
\frac{90}{9}=\sqrt{25x}
Whakawehea ngā taha e rua ki te 9.
10=\sqrt{25x}
Whakawehea te 90 ki te 9, kia riro ko 10.
\sqrt{25x}=10
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
25x=100
Pūruatia ngā taha e rua o te whārite.
\frac{25x}{25}=\frac{100}{25}
Whakawehea ngā taha e rua ki te 25.
x=\frac{100}{25}
Mā te whakawehe ki te 25 ka wetekia te whakareanga ki te 25.
x=4
Whakawehe 100 ki te 25.
