Explications étape par étape :
a) 10^8 x 10 ^-12 = 10^(8-12) =10^(-4)
b)10⁸×10‐³ = 10^(8-3) =10^(5)
c) 10-⁹×10‐⁷= 10^(-9-7) = 10^(-16)
d)10‐¹⁴×10‐¹²= 10^(-14-12) = 10^(-26)
a) 10⁸× 10⁻¹² = 10⁸⁺ ⁽⁻¹²⁾ = 10⁸⁻¹² = 10⁻⁴
b) 10⁸× 10⁻³ = 10⁸⁺⁽⁻³⁾ = 10⁸⁻³ = 10⁵
c) 10⁻⁹× 10⁻⁷ = 10⁻⁹⁺⁽⁻⁷⁾ = 10⁻⁹⁻⁷ = 10⁻¹⁶
d) 10⁻¹⁴× 10⁻¹² = 10⁻¹⁴⁻¹² = 10⁻²⁶
