Sagot :
G = 14 x10^-15 x 0.3 x 10^48 / 24 x (10^5)^4
barre du haut
= 14 x 0.3 x 10^33
barre du bas
= 84 x 10^20
haut = 4.2 x 10^33
4.2/84 = 0.05
on a donc 0.05 x 10^33/10^20
= 0.05 x 10^13
= 5 x 10^11
G = 14 x 10^-15 x 0.3 x 10^48 / 24 x (10^5)^4
= 14 x 0.3 x 10^33
= 4.2 x 10^33
= 4.2/84 = 0.05
= 84 x 10^20
= 0.05 x 10^33/10^20
= 0.05 x 10^13
= 5 x 10^11
