Question

deconponha em fatores primos os numeros 40, 48, 72, 80, 60

Answer 1

40 / 2 = 20
20 / 2 = 10 
10 / 2 = 5
5 / 5 = 1
Logo, 40 = 2³ . 5

48 / 2 = 24
24 / 2 = 12
12 / 2 = 6
6 / 2 = 3
3 / 3 = 1
Logo, 48 = 2^4 . 3

72 / 2 = 36
36 / 2 = 18 
18 / 2 = 9
9 / 3 = 3 
3 / 3 = 1
Logo, 72 = 2³ . 3²

80 / 2 = 40
40 / 2 = 20
20 / 2 = 10
10 / 2 = 5
5 / 5 = 1
Logo, 80 = 2^4 . 5

60 / 2 = 30
30 / 2 = 15 
15 / 3 = 5
5 / 5 = 1
Logo, 60 = 2² . 3 . 5
