Simplifier les expressions litérales suivantes. a) g = 7 x m – 3 b) h = c x c + 5 x c c) k = (8 x s – 5) x (4 – 6 x r) d) m = 7 – d x d + 3 x (5 + d)

bonjour


g = 7 * m - 3 = 7 m  - 3 

h) c² + 5 c² = 6 c² 

k) ( 8 s - 5) ( 4 -  6 r) = 32 s - 48 sr - 20 + 30 r 

m = 7 - d² + 15 + 3 d = - d² + 3 d + 22 

Bonjour,

a)
g = 7 * m - 3
g = 7m - 3

b)
h = c * c + 5 * c
h = c² + 5c

c)
k = (8 * s - 5) * (4 - 6 * r)
k = (8s - 5)(4 - 6r)
k = 8s * 4 - 8s * 6r - 5 * 4 + 6r * 5
k = 32s - 48rs - 20 + 30r

d)
m = 7 - d * d + 3 * (5 + d)
m = 7 - d² + 15 + 3d
m = -d² + 3d + 22
