Bonsoir

 

100 000 = 10^5

1 000 000 000 000 = 10^12

0.0000001 = 10 ^ -7

0.1 = 10^-1

10 = 10^1

100 000 000 000 = 10^11

1 milliard = 10^9

 

A = 10² x 10^6 = 10^2+6 = 10^8

B = 10^3 x 10 ^7 = 10^3+7 = 10^10

C = 10^8 x 10² x 10^12 = 10^8+2+12 = 10^22

D = 10^/ : 10² = 10^5-2 = 10^3

E = 10² : 10^-6 = 10^2+6 = 10^8

F = 10^-4  : 10^5 = 10^-4-5 = 10^-9

G = (10^5)^7 = 10 ^5x7 = 10^35

H = (10^-6)-² = 10^-6x-2 = 10^12

I = (10^4)² x 10 ^-5 : 10^3

= 10^4x2 x 10^-5 : 10^3

= 10^8 x 10^-5 = 10^8-5 = 10^3

10^3 : 10^3 = 10^3-3 = 10^0 = 1
