Explications étape par étape
Bonjour
Calculer et simplifier :
J = -3/5 - 3/5
J = (-3 - 3)/5
J = -6/5
L = 11/6 - 9/4
L = (11 x 2)/(6 x 2) - (9 x 3)/(4 x 3)
L = 22/12 - 27/12
L = (-5/12)
M = 2/3 - (-5/11)
M = (2 x 11)/(3 x 11) + (5 x 3)/(11 x 3)
M = 22/33 + 15/33
M = 37/33
N = -2/3 x (-7/5)
N = 2/3 x 7/5
N = (2 x 7)/(3 x 5)
N = 14/15
