Bonsoir,
74) A= (8-3×2)² ; = (8-6)² ; = 2² ; = 4
B) 8-3×2² ; = 8-3×4 ; = 8-12 ; = -4
C) (8-3)×2² ; = 5×4 ; = 20
D) 8-(3×2)² ; = 8-6² ; = 8-36; = -28
75) A= 2+3×5² ; = 5×25 ; =125
B= -2puissance4+3×(-5)/2² ; = 8+3×(-5)/2² ; = 11×(-5)/2² ; = -55/2² ; -55/4
Voila j'espère que sa t'auras aider. Bonne soirée.;)
