Sagot :
bonjour
D = ( - 2 ) ⁶
E = ( 1/4)² = 1/16
F = ( 1/3) ⁻² = 9
N = (- 2) ⁴ : ( - 2 ) ⁷ = ( - 2 ) ⁻³
O = 2 ⁻⁴ : 2 ⁻⁹ = 2 ⁵
P = - 0.25 ⁴ : - 0.25 ⁻³ = 0.25 ⁷
Q = ( - 3 ) ² x 4 ² = - 12 ²
R = 4 ⁴ : 1/4 ³ = 4 ⁴ : 4 ⁻³ = 4 ⁷
S = 2 ² x 3 ³ x 2 ³ x 3 ⁻³ = 2 ⁵ x 3 ⁰ = 2 ⁵ x 1
bjr
D= (-2³)² = (-2)⁶ (on multiplie les exposants)
E= 1 / 4² = 4⁻² (on change le signe de l'exposant)
F= 1 / 3⁻² = 3²
N= (-2)⁴ / (-2)⁷ = (-2)⁴ x (-2)⁻⁷ = (-2)⁴⁻⁷ = (-2)⁻³ (on ajoute les exposants)
O= 2⁻⁴ / 2⁻⁹ = 2⁻⁴ x 2⁹ = 2⁻⁴⁺⁹ =2 ⁵
P= (-0,25)⁴ / (-0,25)⁻³ = (-0,25)⁴⁺³ = (-0,25)⁷
Q = (-3)² x 4² = (-3 x 4)² = (-12)²
R = 4⁴ x (1 / 4³) = 4⁴ x 4³ = 4⁴⁺³ = 4⁷
S= 2² x 3³ x 2³ x 3⁻³ = 2²⁺³ x 3³⁻³ = 2⁵ x 3⁰ =2⁵ x 1 = 2⁵
