Tohaina
Kua tāruatia ki te papatopenga
4^{n+1}a=36
He hanga arowhānui tō te whārite.
\frac{4^{n+1}a}{4^{n+1}}=\frac{36}{4^{n+1}}
Whakawehea ngā taha e rua ki te 4^{n+1}.
a=\frac{36}{4^{n+1}}
Mā te whakawehe ki te 4^{n+1} ka wetekia te whakareanga ki te 4^{n+1}.
a=\frac{9}{4^{n}}
Whakawehe 36 ki te 4^{n+1}.
