Whakaoti mō a
a=\frac{a_{n}}{2}
Whakaoti mō a_n
a_{n}=2a
Tohaina
Kua tāruatia ki te papatopenga
2a=a_{n}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{2a}{2}=\frac{a_{n}}{2}
Whakawehea ngā taha e rua ki te 2.
a=\frac{a_{n}}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
