Bonjour,

Règle: 1 / a =

Je note "a^n" a à la puissance n

a. 10^8 / 10^4 = 10^(8-4) = 10^4

b. 10^5 / 10^-4 = 10^(5-(-4) = 10^5+4 = 10^9

c. 10^-7 / 10^-2 = 10^(-7-(-2) = 10^-7+2 = 10^-5

d. 10^-3 / 10^9 = 10^(-3-9) = 10^-12

e. 10 / 10^-2 = 10^(1+2) = 10^3

f. 10^3 / 10^3 = 1

g. 10^-3 / 10^3 = 10^-3-3 = 10^-6

h. 10^-5 / 10^-3 = 10^-5+3 = 10^-2
