Sagot :
A. 8,2*x*5,5 = 45.1x
Exercice 2 :
A. 4x*2 = 8x
Exercice 3 :
A.(x*y)*4 = x*y*4
Exercice 4 :
A=3*10+5 = 35
Exercice 5 :
a=3,7 A=6*3,7+0,9 = 23.1
Voila pour chaque exercice tu as un exemple. Tu peux faire la suite.
A = 8.2*5.5 = 45.1
B = 5*0.02 = 0.1
C = 30ax
D = 2.4c
A= 4x*2 = 8x
B = 4*2x = 8x
C = 4x * 2x = 8x²
D = 4x *2y = 8xy
A = 4xy
B = 5a*3x = 15ax
C = 6xy
D = 7abc
E = 20+5x
F = 9y+54-xy-6x
G = a-3+7x
H = 9y+54-xy-6x
I = 11a -6b
A = 3x +5 pour x = 10 A = 30x+5
B = x- 4 = 10-4 = 6
C = 5x-6 = 50-6 = 44
D = x²+1 = 100 +2x+1 = 2x +101
A = 6a +0.9 pour a = 3.7 A = 22.2+0.9 = 23.1
B = 5-a = 5-3.7 = 1.3
C = a² = 13.69
D = 4.5a = 16.65
