Bonjour,
32 ÷ 2 = 16
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
2 ÷ 2 = 1
donc : 32 = 2×2×2×2×2 = 2⁵
110 ÷ 2 = 55
55 ÷ 5 = 11
11 ÷ 11 = 1
donc : 110 = 2 × 5 × 11
45 ÷ 3 = 15
15 ÷ 3 = 5
5 ÷ 5 = 1
donc : 45 = 3×3×5 = 3² × 5
93 ÷ 3 = 31
31 ÷ 31 = 1
donc : 93 = 3 × 31
480 ÷ 2 = 240
240 ÷ 2 = 120
120 ÷ 2 = 60
60 ÷ 2 = 30
30 ÷ 2 = 15
15 ÷ 3 = 5
5 ÷ 5 = 1
donc : 480 = 2×2×2×2×2×3×5 = 2⁵ × 3 × 5
je te laisse faire le dernier en appliquant la même méthode
