Bonjour,
Oui ça se passe bien merci ! :)
Exercice 3 :
A=(3*7)^2 = 21^2 = 441
B=6*2^2*3*5^3 = 6*4*3*125 = 24*375 = 9000
C= (8+5)*3^2 = (8+5)*9 = 13*9 = 117
D=(8+5*3)^2 = (8+15)^2 = 23^2 = 529
E=8-5*3^3 = 8-5*27 = 8-135= -127
F= -3*(4*(-5)^2)^3 = -3*(4*25)^3 = -3*100^3 = -3*1 000 000 = -3 000 000
G= 4+5^-2*6 = 4+0,04*6 =4+0,24 = 4,24
