bonjour jai un dm de math aider moi c vraiment important A=2x(3-1))² B=33-5²-2+8÷(4) C=5-(2+(1-5)x3)

Bonjour,

A = 2 × (3 - 1)²

A = 2 × 2²

A = 2 × 4

A = 8

B = 33 - 5² - 2 + 8 ÷ 4

B = 33 - 20 - 2 + 2

B = 13 - 2 + 2

B = 11 + 2

B = 13

C = 5 - ( 2 + (1 - 5) × 3 )

C = 5 - (2 - 4 × 3 )

C = 5 - (2 - 12)

C = 5 - (-10)

C = 5 + 10

C = 15
