Question

A= 4-1/9×3+1/3
B=(-4/3)×3/7+8×(-4/3)
C=(2/7+5/3)×(10/3-4/7)
D= (18)×5/8×(-2/3)×(-24/9)×(-1/5)

2 Réponse

  • 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
  • A= 4.
    B= -236/21.
    C= 2378/441.
    D= 4
