Bonjour
A = 2⁴ / (2² × 5 )⁵
A = 2⁴/ (2¹⁰ × 5 ⁵)
A = 2 ⁴⁻¹⁰ × 1 / 5⁵
A = 2⁻⁶ × 5⁻⁵
C = (2³ × 2⁻⁴ )² / ( (5³)² × 5⁻⁵)
C = 2⁶ × 2⁻⁸ / (5⁶ × 5⁻⁵)
C = (2⁶⁻⁸)/(5⁶ × 5⁻⁵)
C = 2⁻² / (5⁶⁻⁵)
C = 2⁻²/ 5¹
C = 2⁻² × 5⁻¹
E = (2/5)⁴ × (5²/2)³
E = (2⁴/5⁴) × (5⁶/2³)
E = 2⁴× 5⁻⁴ × 5⁶ × 2⁻³
E = 2⁴⁻³ × 5 ⁻⁴⁺⁶
E = 2¹ × 5²
