Bonjour,
A = 2*(-2) + 2 = -2
D = 4*(-2) + 5 + 4(1 - 5*(-2)) = -8 + 5 + 4(1 + 10) = -8 + 5 + 4*1 + 4*10 = -8 + 5 + 4 + 40 = 41
B = 4(1 - (-2)) = 4(1 + 2) = 4*3 = 12
E = -3*(-2)((-2)*(-2)+7) = -6(4+7) = -6*11 = -66
C = 2*(-2)(6-4*(-2)) = -4(6+8) = -4*14 = -56
F = (2*(-2)+3) (2-5*(-2)) = (-4+3) (2+10) = -1*12 = -12
Voilà, en espérant t’avoir aidé
