D=(10^6/10^-2)×(10^-2/10^-5)×(10^-5/10^4)

=(10^6-(-2))×(10^-2-(-5))×(10^-5-4))

=(10^6+2)×(10^-2+5)×10^-9

=10^8×10^3×10^-9

=10^(8+3-9)

=10^2

=100

Explications étape par étape :

bonjour

D = 10⁶ / 10⁻² × 10⁻²/ 10⁻⁵ × 10⁻⁵/10⁴

D = (10⁶ × 10⁻² × 10⁻⁵ ) / (10⁻² × 10⁻⁵ × 10⁴)

D = 10⁶ / 10⁴

D = 10⁶⁻⁴

D= 10²
