bonjour
A = 2 ⁵ x 5 ⁵ la puissance est commune donc tu multiplies simplement
= 10 ⁵
B = ( - 3 ) ⁴ x 2 ⁴ = même chose
= - 6 ⁴
C = 10 ⁻⁷ x 2 ⁻⁷
= 20 ⁻⁷
D = ( - 2 ) ⁻³ x ( - 3 ) ⁻³
= 6 ⁻³
E = 2 ⁵ / 5 ⁵ = (2/5) ⁵
F = ( - 3 )⁴ : 2 ⁴ = - 1.5 ⁴
G = 10 ⁻⁷ : 2 ⁻⁷ = 5 ⁻⁷
H = ( - 2 ) ⁻³ : ( - 3 ) ⁻³ = ( 2/3 ) ⁻³
bon WE
