bonjour pouvez vous maidez svp :) regardez l'image ​

Bonjour

A = 2 x (5 + 4)^2

A = 2 x 9^2

A = 2 x 81

A = 162

B = 16/(3 - 1)^2

B = 16/2^2

B = 16/4

B = 4

C = 2 x (1 - 5)^3

C = 2 x (-4)^3

C = 2 x (-64)

C = -128

D = 3 x (1 - 3)^5 - 2^2 x (3 + 2)

D = 3 x (-2)^5 - 4 x 5

D = 3 x (-32) - 20

D = -96 - 20

D = -116

E = (5 - 2 x 3)^4 / (2 - 3)^5

E = (5 - 6)^4 / (-1)^5

E = (-1)^4 / (-1)

E = -1
