    4x (5 -(-2)^4) / 2^3

    4 x ( 5 -16)/8

    4 x (-11) /8

    -44/8

    -11/2


    B = 4/3 -5/4 x 2/5*3

    B  = 4/3 -1/4 x 2/3

    B = 4/3 -1/2x 1/3

    B = 4/3 -1/6

    B = 8/6 -1/6

    B = 7/6

    Calculer :

    A = 4 x (5 - (4 - 6)^4)/2^3

    A = 4 x [5 - (-2)^4] / 8

    A = (5 - 16) / 2

    A = (-11)/2


    B = 4/3 - 5/4 x 2/15

    B = 4/3 - 5/15 x 2/4

    B = 4/3 - 1/3 x 1/2

    B = 4/3 - 1/6

    B = 8/6 - 1/6

    B = 7/6
