Bonjour !

A = 2 x (-4)²  = 2 x 16 = 32

B = (3x (-2))² = (-6)² = 36

C= 2-3²  = 2 - 9 = -7

D = (2-3)² = (-1)² = 1

E = (-3)² x 2 - 13 = 9 x 2 - 13 = 18 - 13 = 5

F = (2x 3-7)² + 2² = (6-7)² + 4 = (-1)² + 4 = 1 + 4 = 5

G= -3² x (3-2 x 5) = - 9 x (3-10) = - 9 x (-7) = 63

H = 5²-9² = 25 - 81 = - 56

I = (2-3)²-(-3)² = (-1)² - 9 = 1 - 9 = -8

J = 2 x (5-3²)² = 2 x (5 - 9)² = 2 x (-4)² = 2 x 16 = 32

K = (-2+2 x 3)² = (- 2 + 6)² = 4² = 16

L = (3-6)² x (-2) = (-3)² x (-2) = 9 x (-2) = - 18

M = [(5-9)² - 3²]² = [(-4)² - 9]² = (16 - 9)² = 7² = 49

Bonne journée :)
