A = ( - 2 ) ³ + 4 x 2 ⁴ - 3 ²

Bonjour,
A = (-2)³ + 4 × 2⁴ - 3²
= -8 + 4 × 16 - 9
= -8 + 64 - 9
= 47
B = (4 - 5³) / (2³ × 2 + 3 + 5²)
= (4 - 125) / (8 × 2 + 3 + 25)
= -121 / (16 + 3 + 25)
= -121 / 44
= -(11 × 11) / (4 × 11)
= -11/4
C = 3 - 5² × (21 - 3 × 2²)⁴
= 3 - 25 × (21 - 3 × 4)⁴
= 3 - 25 × (21 - 12)⁴
= 3 - 25 × 9⁴
= 3 - 25 × 6 561
= 3 - 164 025
= -164 022
