bonjour
E = 10 ⁷ x 10 ³ : 10 ⁴
= 10 ⁴ : 10 ⁴
= 10 ⁰ = 1
F = 10 ⁹ x 10 ⁻² : 10 ⁵ x 10 ⁻¹
= 10 ⁷ : 10 ⁴
= 10 ³
H = ( 10 ² ) ⁶ : 10 ⁻² x 10 ⁻³
= 10 ¹² : 10 ⁻⁵
= 10 ¹⁷
A = 1 + 3 ¹ + 3 ² = 1 + 3 + 9 = 13
B = ( 1 - 3 ³) : ( 1 - 3 ) = ( 1 - 27 ) : ( - 2) = - 26/-2 = 13
C = 1 + 4 ¹ + 4 ² + 4 ³ = 1 + 4 + 16 + 64 = 85
D = ( 1 - 4 ⁴) : ( 1 - 4) = ( 1 - 256 ) : - 3 = - 255 /-3 = 85
E = 1 + 5 ¹ + 5 ² + 5 ³ + 5 ⁴ = 1 + 5 + 25 + 125 + 625 = 781
F = ( 1 - 5 ⁵ ) : ( 1 - 5) = (1 - 3 125 ) : - 4 = - 3124 / - 4 = 781
voilà je pense que tu peux finir
