bonjour
A = 5 ⁻⁴ = 1 / 625
B = ( 2/3 )⁴ = 16/81
C = ( 2/3 ) ⁻⁴ = 81 /16
D = 7 ² x 7 ⁵ = 7 ⁷
E = ( - 3 ) ⁻⁷ x ( - 3 )² = ( - 3 ) ⁻⁵
F = 5 ⁵/5² = 5 ³
G = 4² / 4 ⁻⁵ = 4 ⁷
H = ( 10 ³)² = 10 ⁶
I = ( 10 ⁻²) ⁵ = 10 ⁻¹⁰
J = 7 ⁶ x 9 ⁶ = 63 ⁶
K = ( - 8 ) ⁹ x ( - 5 ) ⁹ = 40 ⁹
250 = 2.5 x 10 ²
0.54 = 5.4 x 10 ⁻¹
0.0128 = 1.28 x 10 ⁻²
5 423 900 = 5.423900 x 10 ⁶
S = 0.45
T = 0.000 078
U = 5.457
V = 55 398 000
