1. Réponse Lau16
A = 4 - 1/9 * 3 + 1/3
A = 4 - 1/3 + 1/3
A = 4
B = (-4/3) * 3/7 + 8 * (-4/3)
B = -12/21 - 32/3
B = -12/21 - 224/21
B = -236/21
C = (2/7 + 5/3) * (10/3 - 4/7)
C = (6/21 + 35/21) * (70/21 - 12/21)
C = 41/21 * 58/21
C = 2378/441
D = 18 * 5/8 * (-2/3) * (-24/9) * (-1/5)
D = 90/8 * 2/15 * (-24/9)
D = 180/120 * (-24/9)
D = 4320/1080
D = 4 -
