Kalau tau dijawab yah, makasih Sayank:)

1menit = 81.000.000 =81 x 10^6 = 3^4 x 10^6

senin – jumat = 12 jam/hari = 5 hari x 12 jam = 5 x 2^2 x 3

sabtu – minggu = 18 jam/hari = 2 hari = 2 x 9 x 2 = 2^2 x 3^2

1 jam = 60 menit = (6 x 10) x 81,000,000 = (2 x 3 x 10) x( 3^4 x 10^6)

= 2 x 3^5 x 10^7

senin-jumat = (5 x 2^2 x 3) x (2 x 3^5 x 10^7) = 5 x 2^3 x 3^6 x 10^7

sabtu-minggu = (2^2 x 3^2) x (2 x 3^5 x 10^7) = 2^3 x 3^7 x 10^7

jadi dlm 1 minggu = (5 x 2^3 x 3^6 x 10^7) + (2^3 x 3^7 x 10^7)
