Bonsoir

Explications étape par étape

A = (3/4)^2

A = 3^2/4^2

A = 9/16

B = (1 - 5^2)/(1 - 5)^2

B = (1 - 25)/(-4)^2

B = (-24)/16

B = (-8 x 3)/(8 x 2)

B = -3/2

E = (1/2 - 3/4) x 16/9

E = (2/4 - 3/4) x 16/9

E = (-1/4) x 16/9

E = -16/4 x 1/9

E = -4/9

F = 1/2 - 3/4 x 16/9

F = 1/2 - 3/9 x 16/4

F = 1/2 - 1/3 x 4

F = 3/6 - 4/3

F = 3/6 - 8/6

F = -5/6
