Sagot :
Bonjour,
K = 5x * 3x
K = 15x²
L = 5x + 5x + 5x
L = 15x
M = 5x * 5x * 5x
M = 125x³
N = x² * x
N = x³
P = x² + x²
P = 2x²
Q = x² + x
R = a + a + a + b + b
R = 3a + 2b
S = a * a * a * b * b
S = a³ * b²
bonjour
K = (5*3)x = 15x
L = (5+5+5)x = 15x
M = (5*5*5)x = 25*5 x = 125x
N = x ² * x = x³
P = x² + x² = 2x²
Q = x² + x = x ( x + 1 )
R = 3a + 2b
S = a³ * b²
bonne journée
