Bonjour,A = (75 x 10^(-7) x (-2) x (10^3)^2)/(50 x 10^3 x (-0,1) x 10^(-5))
A = [(75 x -2) / (50 x (-0,1))] x [10^(-7+6-3+5)]
A = (150/5) x 10^1
A = 30 x 10^1
A = 3 x 10^2
A = 300
B = (-4 x 10^(-2)^(-3) + 4 x 10^6)/(6/5 + 0,8)
B = (-4 x 10^6 + 4 x 10^6) / (6/5 + 8/10)
B = 0 / (12/10 + 8/10)
B = 0
B est un nombre entier
C = (40 x 10^15 x 9 x (10^3)^2) / (30 x 10^21 x 21) = 4/7
C = [(40 x 9) / (30 x 21)] x (10^15 x 10^6 x 10^(-21))
C = (36/33) x 10^(15+6-21)
C = (12/11) x 10^0
C = 12/11
C n’est pas égal à 4/7
