Exercice 58 :

A = 3 + 4²
Pour que tu comprennes :
A = 3 + (4 x 4)
A =  3 + 16
A = 19

B = (3 + 4)²
B = 3 x 3 + 4 x 4
B = 9 + 16
B = 25

C = 3 - 4²
C = 3 - (+16)
C = 13

D = (-3 - 4)²
D = 9 - 16
D = 7

E = 3 x 4²
E = 3 x 16
E = 48

F = (3 x 4)²
F = 12²
F = 12 x 12
F = 144

Exercice 59 :

A = 2³ + 3²
A = (2 x 2 x 2) + (3 x 3)
A = 8 + 9
A = 17

B = 2³ x 3²
B = (2 x 2 x 2) x (3 x 3)
B = 8 x 9
B = 72

C = 2 x 3²
C = 2 x (3 x 3)
C = 2 x 9
C = 18

D = 2⁴ + 3⁴
D = (2 x 2 x 2 x 2) + (3 x 3 x 3 x 3)
D = 16 + 81
D = 97

E = 5³ - 4³
E = (5 x 5 x 5) - (4 x 4 x 4)
E = 125 - 64
E = 61

F = (-2)⁵ + 3³
F = (-2 x -2 x -2 x -2 x -2) + (3 x 3 x 3)
F = -10 + 27
F = 17
