Bonjour ! ;)

Exercice 5 :
A = 5 * 10³ * 10⁵
A = 5 * 10³⁺⁵
A = 5 * 10⁸
B = 3 * 10⁻³ * 7 * 10⁸
B = 3 * 7 * 10⁻³⁺⁸
B = 21 * 10⁵
B = 2,1 * 10¹ * 10⁵
B = 2,1 * 10¹⁺⁵
B = 2,1 * 10⁶
C = [tex]\frac{8*10^{6} }{2*10^{4} }[/tex]
C = [tex]\frac{8}{2}[/tex] * 10⁶⁻⁴
C = 4 * 10²
D = [tex]\frac{5*10^{4}*6*10^{2} }{10^{5} }[/tex]
D = 5 * 6 * [tex]\frac{10^{4+2} }{10^{5} }[/tex]
D = 30 * [tex]\frac{10^{6} }{10^{5} }[/tex]
D = 30 * 10⁶⁻⁵
D = 30 * 10¹
D = 3,0 * 10¹ * 10¹
D = 3,0 * 10¹⁺¹
D = 3,0 * 10²
E = ( 5 * 10⁴ )²
E = 5² * 10⁴ˣ²
E = 25 * 10⁸
E = 2,5 * 10¹ * 10⁸
E = 2,5 * 10¹⁺⁸
E = 2,5 * 10⁹
F = ( 2 * 10⁻⁴ )³
F = 2³ * 10⁻⁴ˣ³
F = 8 * 10⁻¹²
