Bonjour !

9.35 × 10^-12 + 0.047 × 10^-10 - 51.3 × 10^-14 = 9.35 × 10^-12 + 4.7 × 10^-12 - 0.513 × 10^-12 = (9.35 + 4.7 - 0.513) * 10^-12 = 13.537 * 10^-12 = 1.3537 * 10^-11

Voilà !

Bonjour,

A=9,35*10⁻¹²+0,047*10⁻¹⁰-51,3*10⁻¹⁴

A=10⁻¹⁴(9,35*10²+0,047*10⁴-51,3)

A=10⁻¹⁴(935+470-51,3)=1353,7*10⁻¹⁴

A=1,3537*10⁻¹¹
