Bonjour,

(8h -2) =  0

8h = 2

h = 2/8 = 1/4

ou

-4h+3 = 0

-4h = -3

h -3/64 = 3/4

T² = 25

T= √25 = 5

K² = 19

K = √19

10H = -9

H = -9/10 = 0,9

8L-2L =-3 -5

6L = -8

L = -8/6 =  -4/3

(j’ai pas fait le 1 mais jai fais tout le reste)

2.

T²-25 = 0

T² = 25

T = 5

3.

K²-19 =0

K² = 19

K = 4,35

4.

10H+9 = 0

10H = 0-9

10H = -9

H = -9/10

H = -0,9

5.

8L+5 = 2L-3

8L-2L = -5-3

6L = -8

L = -8/6

L = 1,33
