Explications étape par étape :

Bonsoir,

Simplifier les écritures :

A = 2V2 x V50

A = 2V(2 x 50)

A = 2V100

A = 2V(10^2)

A = 2 x 10

A = 20

B = V15 x 3 x V10

B = 3 x V(15 x 10)

B = 3 x V(3 x 5 x 2 x 5)

B = 3 x 5V6

B = 15V6

C = 2V27 x 6V3

C = 2 x 6 x V(27 x 3)

C = 12 x V(3^3 x 3)

C = 12 x V(3^2 x 3^2)

C = 12 x 3 x 3

C = 108

D = 3V2 x V8 x 2V2

D = 3 x 2 x V(2 x 8 x 2)

D = 6 x V(2^2 x 2^2 x 2)

D = 6 x 2 x 2 x V2

D = 24V2
