Salut,

exercice 2 donc.

E = 0.000000000000037

E = 3.7 x 10^-14

F = 58 300 000 000

F = 5.83 x 10^10

G = 6.2 x 10^25 x 5 x 10^-14

G = 31 x 10^11

H = (2 x 10^7 x 35 x 10^-3) / 5 x 10^-3

H = 70/5 x (10^4 / 10^-3)

H = 14 x 10^7

H = 1.4 x 10^8

Si tu as des questions, demande moi. A+

Meilleure réponse !

Bonsoir
E = 0.000000000000037
E = 3.7 x 10^-14

F = 58 300 000 000
F = 5.83 x 10^10

G = 6.2 x 10^25 x 5 x 10^-14
G = 31 x 10^11

H = (2 x 10^7 x 35 x 10^-3) /5 x 10^-3
H = 70/5 x (10^4 / 10^-3)  ; H = 14 x 10^7  ; H = 1.4 x 10^8



Exercice 3
écriture décimale

J = 650 x 10^-6 = 0,00065
K = 1,14356 x 10^-3 = 0,00114356
