Whakaoti mō b_15
b_{15}=16200
Tohaina
Kua tāruatia ki te papatopenga
8100=\frac{1}{2}b_{15}
Tātaihia te 90 mā te pū o 2, kia riro ko 8100.
\frac{1}{2}b_{15}=8100
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
b_{15}=8100\times 2
Me whakarea ngā taha e rua ki te 2, te tau utu o \frac{1}{2}.
b_{15}=16200
Whakareatia te 8100 ki te 2, ka 16200.
