4!+5!
12!
Nt : prenjon memang menyakitkan T-T
Jawab:
1. 4!+5! = 144
= 4 x 3 x 2 x 1
= (12 x 2) x 1
= (24 x 1)
= 24
---------------
= 5 x 4 x 3 x 2 x 1
= (20 x 3) x 2 x 1
= (60 x 2) x 1
= (120 x 1)
= 120
---------------
24 + 120 = 144
2.12!
= 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= (132 x 11) x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= (1.452 x 10) x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= (14.520 x 9) x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= (130.680 x 8) x 7 x 6 x 5 x 4 x 3 x 2 x 1
= (1.045.440 x 7) x 6 x 5 x 4 x 3 x 2 x 1
= (7.318.080 x 6) x 5 x 4 x 3 x 2 x 1
= (43.908.480 x 5) x 4 x 3 x 2 x 1
= (219.542.400 x 4) x 3 x 2 x 1
= (878.169.600 x 3) x 2 x 1
= (2.634.508.800 x 2) x 1
= (5.269.017.600 x 1)
= 5.269.017.600
koreksi kalau ada yg salah:>
