Kua tāruatia ki te papatopenga
\sqrt{m+15}+1-1=5-1
Me tango 1 mai i ngā taha e rua o te whārite.
\sqrt{m+15}=5-1
Mā te tango i te 1 i a ia ake anō ka toe ko te 0.
\sqrt{m+15}=4
Tango 1 mai i 5.
m+15=16
Pūruatia ngā taha e rua o te whārite.
m+15-15=16-15
Me tango 15 mai i ngā taha e rua o te whārite.
m=16-15
Mā te tango i te 15 i a ia ake anō ka toe ko te 0.
m=1
Tango 15 mai i 16.
