3 x ( 360 ÷ 30 ) =
3 x 12 =
34
531.441 virus
diketahui
u1=a=3
r=3
n=6÷1/2=12
ditanya
jumlah virus setelah 6 jam=....? ===>>U12=....?
jawab
[tex]un = a \times {r}^{n - 1} \\ u12 = 3 \times {3}^{12 - 1} \\ = 3 \times 3 {}^{11} \\ = {3}^{12} \\ = 531441[/tex]
jadi, jumlah virus setelah 6 jam menjadi 531.441 virus
