est-ce que vous pouvez m'aider en maths , c'est urgent! Merci d'avance
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
