E = 60 x 10 ¹² x 4 x 10 ⁻²⁶
E = 240 x 10 ⁻¹⁴ = 2.4 x 10 ⁻¹²
F = ( 500 000 000)² = 2.5 x 10 ¹⁷
G = 12 x 10 ³² = 1.2 x 10 ³³
H = 490 x 10 ⁶ sur 21 x 10 ³
H = 490/21 x 10 ³ = 70/3 x 10 ³
I = 105 x 10 ⁶ sur 21 x 10 ⁻¹
I = 5 x 10 ⁷ = 50 000 000
J = 60 x 10 ³ sur 120 x 10 ⁻³
J = 0.5 x 10 ⁰
J = 0.5
K = 3.6 x 10 ² x 10 ⁻¹² sur 0.2 x 10 ⁻⁷
K = 3.6 x 10 ⁻¹⁰ sur 0.2 x 10 ⁻⁷
K = 18 x 10 ⁻³
K = 1.8 x 10 ⁻² = 0.018
