bonjour,
D = 49 x 10 ³⁵ : 7 x 10 ³⁴
= 7 * 10
= 70
E = 1 200 x 10 ⁸ : 6 x 10 ⁷
= 200 x 10
= 2 000
= 2 * 10 ³
F = 1 050 * 10 ⁻⁵ : 35 * 10 ⁻³
= 30 x 10 ⁻²
= 0.3
= 3 * 10 ⁻¹
G = 105 x 10 ¹³ : 42 * 10 ¹⁰
= 2.5 * 10 ³
= 2 500
H = 1.6 * 10 ⁻¹² : 4 * 10 ⁻⁹
= 0.4 * 10 ⁻³
= 0.000 4
= 4 * 10 ⁻⁴
I = 3.9 * 10 ⁻⁴ : 3 * 10 ⁻⁵
=1.3 * 10
= 13
