bonsoir
0.4 x 100 ³ x 200 x 10 ²
= 0.4 x ( 10 ²) ³ x ( 2 x 10² ) x 10 ²
= 0.4 x 10 ⁶ x 2 x 10 ² x 10 ²
= 0.8 x 10 ¹⁰
= 8 x 10 ¹¹
0.003 x 10 ⁻³ / 10 000
= 0.003 x 10 ⁻³ / 10 ⁴
= 0.003 x 10 ⁻⁷
= 3 x 10 ⁻¹⁰
0.7 x ( 0.01 )³ = 0.7 x 10 ⁻⁶ = 7 x 10 ⁻⁷
0.01396 = 1.396 x 10 ⁻²
0.172 x 10 ⁵ = 1.72 x 10 ⁴
continue
43 x 10 ⁻⁴ = 0.004 3
tu prends la calculatrice pour celui là
A = 3.6 x 10 ⁻⁶
B = 1.2372 x 10 ⁵
C = 1.37 x 10 ³⁰ - 1.27 x 10 ³⁰ = 1 x 10 ²⁹
D = 1.2 x 7 x 10 ⁻⁴ x 10 ⁻⁶ x 3 x 10 ³
= 25.2 x 10 ⁻⁷
= 2.52 x 10 ⁻⁶
E = 20 x 10 ⁶ / 3 x 10 ⁶
= 20/3 x 10 ⁰ = 20/3
allez finis
