Explications étape par étape
Bonjour,
A = 2 × 2 × 2 × 2 × 5 × 5 × 5 × 5 = 2⁴ × 5⁴
B = 25 × 10 × 5 × 8
= 5×5 × 2×5 × 5 × 2×2×2
= 5 × 5 × 5 × 5 × 2 × 2 × 2 × 2
= 5⁴ × 2⁴
C = 625 × 512
= 5×5×5×5 × 2×2×2×2×2×2×2×2×2
= 5⁴ × 2⁹
D = 2 × 2 × 2 × 3 × 7 × 7
= 2³ × 3¹ × 7²
E = 32 × 21 × 12
= 2×2×2×2×2 × 3×7 × 3×2×2
= 2⁷ × 3² × 7¹
