Bonjour,quelqu’un pourrait m’aider à l’exercice de math svp merci d’avance

Bonsoir,

1)

Z = 3

A = Z - 1 = 3 - 1 = 2

B = A² = 2² = 4

C = Z + 1 = 3 + 1 = 4

D = C² = 4² = 16

Z = B + D = 4 + 16 = 20

Donc Z = 20.

2)

Z = 3

Z = Z - 1 = 3 - 1 = 2

A = Z² = 2² = 4

Z = Z + 1 = 2 + 1 = 3 #On garde la dernière valeur de Z.

B = Z² = 3² = 9

Z = A + B = 4 + 9 = 13

Donc Z = 13.

3)

Z = 3

Z = Z - 1 = 3 - 1 = 2

B = Z² = 2² = 4

A = Z + 1 = 2 + 1 = 3

C = A² = 3² = 9

Z = B + C = 4 + 9 = 13

Donc Z = 13.

Bonne soirée,

Thomas
