bonjour
A = 8 ² x 8 ⁻³ x 8 ⁷
A = 8 ⁶
B = 11 ⁻⁸ x 11 ⁷/ 11 ⁻⁴
B = 11 ⁻¹ / 11 ⁻⁴
B = 11 ³
C = ( - 3 ) ⁶ x ( - 3 ) ⁻⁸ / ( - 3 ) ⁻⁷
C = ( - 3 ) ⁻² ) / ( - 3 ) ⁻⁷
C = ( - 3 ) ⁵
Bonjour,
A = 8² × 8⁻³ × 8⁷ = 8²⁺⁽⁻³⁾⁺⁷ = 8⁶
B = 11⁻⁸ × 11⁷/11⁻⁴ = 11⁻⁸⁺⁷⁻⁽⁻⁴⁾ = 11³
C = ((-3)⁶ × (-3)⁻⁸) / (-3)⁻⁷ = (-3)⁶⁺⁽⁻⁸⁾⁻⁽⁻⁷⁾ = (-3)⁵
