Exercice 1 :
A = 8 * (- 2)³ - 10
A = 8 * (- 8) - 10
A = - 64 - 10
A = - 74
B = 4 * 2⁴ + 5
B = 4 * 16 + 5
B = 64 + 5
B = 69
C = - 5² - 7 * (- 9)
C = - 5² + 63
C = - 25 + 63
C = 38
Exercice 2 :
a. Pour y = 3
D = 4y² - 5
D = 4 * 3² - 5
D = 4 * 9 - 5
D = 36 - 5
D = 31
b. Pour y = - 1
D = 4y² - 5
D = 4 * (- 1)² - 5
D = 4 * 1 - 5
D = 4 - 5
D = - 1
c. Pour y = - 3
D = 4y² - 5
D = 4 * (- 3)² - 5
D = 4 * 9 - 5
D = 36 - 5
D = 31
d. Pour y = 3/5
y = 0,6
D = 4y² - 5
D = 4 * 0,6² - 5
D = 4 * 0,36 - 5
D = 1,44 - 5
D = - 3,56
