72000000\times 10^{n}=72000000000000000
Whakamahia ngā ture taupū me ngā taupū kōaro hei whakaoti i te whārite.
10^{n}=1000000000
Whakawehea ngā taha e rua ki te 72000000.
\log(10^{n})=\log(1000000000)
Tuhia te tau taupū kōaro o ngā taha e rua o te whārite.
n\log(10)=\log(1000000000)
Ko te taupū kōaro o tētahi tau ka hīkina ki tētahi pū ko te pū whakarea ki te taupū kōaro o taua tau.
