Bonjour pourriez vous m'aidez s'il vous plaît :) ( regarder la photo ) ​

O = 10^7*10^2 / 10^3
O = 10^9/10^3
O = 10^6

N = 10^1*10^2 / 10^3
N = 10^3/10^3
N = 10

B = 10^4 / 10^7*10^3
B = 10^4 / [10^10
B = 10^-6

É = (10^5)^5 / 10^5
É = 10^25/10^5
É = 10^20

I = 10^4*10^2/10^9
I = 10^6/ 10^9
I = 10^-3

J = 10^8 / 10^1*10^2
J = 10^8/ 10^3
J = 10^11

U = (10^3)^4 / 10^5
U = 10^12/10^5
U = 10^7

E = (10^2)^4 / 10^9
E = 10^8/10^9
E = 10^-1
