Exercice 6
Écris le plus simplement possible.
A = 3 xa xb
B = 3 x a + 3 x b
D = 5 + 3 x b
E = 5 x a + 3 + 2
G= 7 xa x b x 3 H = 7 + a x b + 3
J = (2,5 - 1) xa x b
C = 8 x a x2
F = 2 x 3 xa x (b x c)
1 = 3 X (2 x a + b) x 5

    Explications étape par étape

    A = 3 xa xb

    =3abx²

    B = 3 x a + 3 x b

    =3x(a+b)

    D = 5 + 3 x b

    =5+3bx

    E = 5 x a + 3 + 2

    =5ax+5

    =5(ax+1)

    G= 7 xa x b x 3

    =21abxx²

    H = 7 + a x b + 3

    =10+abx

    J = (2,5 - 1) xa x b

    =1.5abx²

    C = 8 x a x2

    =16ax²

    F = 2 x 3 xa x (b x c)

    =6abcx²x²

    1 = 3 X (2 x a + b) x 5

    =(6xa+3b)x5

    =(30ax²+15bx)
