Bonjour,
Exercice 1 :
C = 10^6 × 10^-8
C = 10^(6+(-8))
C = 10^-2
D = (10^-1)^-3
D = 10^(-1×(-3))
D = 10^3
E = 10^-2/10^2
E = 10^(-2-2 )
E = 10^-4
F = 10^2 × 10^3 × 10
F = 10^(2+3+1)
F = 10^6
Exercice 2 :
B = 21 600 = 2,16 × 10^4
C = 0,012 = 1,2 × 10^-2
D = 58,4×10^2 = 5,84×10×10^2 = 5,84×10^3
E = 0,147×10^-1 = 1,47×10^-1×10-1 = 1,47×10^-2
Exercice 3 :
E = 3,35 × 10^-2
F = 7,2 × 10^3
G = 2×10^-4
H = 9,91×10^-3
G < H < E < F
