DM de Mathématiqaes 2 Pour le Exercice 1. (10) On donne a = -2; b = +5; c= -3 et d = 4. Calculer, en détaillant : A = ac ; B = bc ; : C = a + b +c+d D = a-b-c-d :
E= a-c-bd ; F = F = a - c а с b + d

Qui peut m aider merciqui peut m'aider ​

Sagot :

Coucou

A = ac
A = a * c
A = (-2) * (-3)
A = 6

B = bc
B = b * c
B = 5 * (-3)
B = -15

C = a + b + c + d
C = -2 + 5 + (-3) + 4
C = -2 + 5 - 3 + 4
C = 4

D = a - b - c - d
D = -2 - 5 - (-3) - 4
D = -2 - 5 + 3 - 4
D = -8

E = a - c - bd
E = -2 - (-3) - [5 * 4]
E = - 2 + 3 - 20
E = -19

F = a - cacb + d
F = -2 - [(-3) * (-2) * (-3) * 5]
F = - 2 - [-90]
F = -2 + 90
F = 88
