qui peut m'aider svp merçi c'est en maths A= 5x12+17+6:2 B= 13+6x3-4x2 C= 9x(11-15) x2-1 D = (-1)x4x(8+7)x0,25 E= 3+5au carré F= 6x(9-3)+7+11x(-2) G= 11+2x(7+3x

Bonjour

A= 5x12+17+6:2

A = 60 + 17 + 3

A = 80

B= 13+6x3-4x2

B = 13 + 18 - 8

B = 23

C= 9x(11-15) x2-1

C = 9 x (- 4) x 2 - 1

C = - 36 x 2 - 1

C = - 72 - 1

C = - 73

D = (-1)x4x(8+7)x0,25

D = - 4 x 15 x 0,25

D = - 60 x 0,25

D = - 15

E= 3+5au carré

E = 3 + 25

E = 28

F= 6x(9-3)+7+11x(-2)

F = 6 x 6 + 7 - 22

F = 36 - 15

F = 21

G= 11+2x(7+3x4)

G = 11 + 2 x (7 + 12)

G = 11 + 2 x 19

G = 11 + 38

G = 49

H= 5-19+6-25

H  = - 33

I = 36:4 x (-7)

I = 9 x (- 7)

I = - 63

J = (-101) x 6,3x0 x (-40)

J = 0

K= (9,6)x (4-7) x (9-11)

K = 9,6 x (- 3) x (- 2)

K = 9,6 x 6

K = 57,6

L = (-3)au cube

L = - 27.
