Réponse:
A = -580
B = 204
C = 35
D = 1969
E = -41
F = 324
Explications étape par étape:
A = (-20 - 38) x 10 = -58 x 10 = - 580
B = (3 - 7) x (-52 + 1) = -4 x -51 = 204
C = 2^0 + 6^2 - 2^1 = 1 + 36 - 2 = 35
D = 1x10^3 + 9x10^2 + 6x10^1 + 9x10^0 = 1x1000 + 9x100 + 6x10 + 9x1 = 1000 + 900 + 60 + 9 = 1969
E = (1 - 5)^3 + 23 = (-4)^3 + 23 = -64 + 23 = -41
F= (-10 + 20) x (6^2 - 3) - 6 = 10 x (36 - 3) - 6 = 10 x 33 - 6 = 330 - 6 = 324
