Explications étape par étape

Bonjour

A = 10^2/10^8 = 10^(2-8) = 10^(-6)

B = 10^-2 + 10^-4 = 0,01 + 0,0001 = 0,0101 = 1,01 x 10^(-2)

C = 10^3 x 10-9 = 10^(3-9) = 10^(-6)

D = 1/10^6 = 10^(-6)

E = 0,01 x 10^(-4) = 1 x 10^(-2) x 10^(-4) = 10^(-2-4) = 10^(-6)

F = 10^-8 / 100 = 10^(-8)/10^(2) = 10^(-8-2) = 10^(-10)

G = 0,001/10^3 = 1 x 10^(-3) / 10^3 = 10^(-3-3) = 10^(-6)

H = 10^(-9) x 1000 = 10^(-9) x 10^3 = 10^(-9+3) = 10^(-6)

I = 10^(-12) x (10^12 + 10^6) = 10^(-12+12) + 10^(-12+6) = 10^0 + 10^(-6) = 1,000001 x 10^(-6)
