Tohaina
Kua tāruatia ki te papatopenga
\frac{3\sqrt{b}}{3}=\frac{6\sqrt{7}}{3}
Whakawehea ngā taha e rua ki te 3.
\sqrt{b}=\frac{6\sqrt{7}}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
\sqrt{b}=2\sqrt{7}
Whakawehe 6\sqrt{7} ki te 3.
b=28
Pūruatia ngā taha e rua o te whārite.
Ngā Tauira
whārite tapawhā
