A = 2 x 9² = 2 x 18 = 36

B = 16/(2)² = 16:4=4

C = 2 x (-4)³ = 2x(-64) = -128

D = 2 + 2 x 81 = 2 + 162 = 164

E = (2 + 16x3) (27-1) =  50 x 26 = 1300

F = 3 x (-2)⁵ - 4 x 5 = 5x(-32) - 20 = -180

G = (-1)⁴ / (-1)⁵ tu trouves

Bonjour,

A=2*9²

A=2*81

A=162

B=16/2²

B=16/4

B=4

C=2*(-4)²

C=2*16

C=32

D=(2+(-6))

D=-4⁴

D=-256

E=(2+-16*3)*5

E=2+(-48)*5

E=-46*5

E=-230
