Bonsoir

A = 2⁴ x 5 ⁵
B = 25 x 10 x 5 x 8
B = 5² x 2 x 5 x 5 x 2³ = 5 ⁴ x 2 ⁴

C = 625 x 512
C = 25 x 25 x 2 ⁹
C = 5⁴ x 2⁹

D = 2³ x 3 x 7²

E = 32 x 21 x 12
E = 2 x 16 x 3x 7x 3x 4
E = 2⁵ x 3² x 7 x 2²
E = 2⁸ x 3² x 7

F = 12 x 21 x 49
F = 3 x 4 x 7x 3 x 7 x
F = 2² x 3² x 7³

G = 42
G = 6 x 7
G = 2 x 3 x 7
