Bonjour merci d’avance.

Bonjour !

a) (10^9)^4 = 10^36

b) 10^-4/10^9 = 10^-13

c) 10^12×10^-8×10^5 = 10^9

d) 10^-6/10^6 = 10^-12

e) 10^41x10^7/10^-39 = 10^87

f) 10^-9×10^12 = 10^3

g) 10^-7/10^8 = 10^-15

h) (10^-3)^-6 = 10^18

I) 10^10/10^-5 = 10^15

J) 10^21/10^-4×10^-18 = 10^43

Bon courage.
