A = 5/8 - 3 x 5/4
A = 5/8 - 15/4
A = 5/8 - 15 x 2 / 4 x 2
A = 5/8 + 30/8
A = 35/8

D = 6 + 4 x 3² +(2³ - 3²) x 4
D = 6 + 4 x 9 + (16 - 9) x 4
D = 6 + 36 + (7) x 4
D = 6 + 36 + 28
D = 70

Je ne vois pas bien la consigne ...

A = 3² x 3⁻⁴
A = 9 x 81
A = 729

F = 2⁵ x 2⁻⁷ x 2⁸
F = 32 x - 128 x 256
F = - 4096 x 256
F = 1048576
