ada yg tau nomor 1 gak ? mohon bantuan

Nt = No * 2^kt
No = 2000
N10 = 5000
karena Nt = No * 2^kt
jadi N10 = No * 2^10k
5000 = 2000 * (2k)^10
5/2 = (2k)^10
2k = (5/2)^1/10

N20 = No * 2^20k
N20 = 2000 * (2k)^20
N20 = 2000 * ((5/2)^10)^20

N20 = 2000 * (5/2)^2
= 2000 * 25/4
= 2000 * 2,5
= 12.500 bakteri

semoga membantu :)
