Bonjour :
Mettre sous la forme an :
C = 4⁸×4⁵/(4²)⁵
C = 4⁸⁺⁵/4²ˣ⁵
C = 4¹³/4¹⁰
C = 4¹³⁻¹⁰
C = 4³
D = 5⁻¹²×5×25⁴
D = 5⁻¹²⁺¹×25⁴
D = 5⁻¹¹×25⁴
D = 5⁻¹¹×(5×5)⁴
D = 5⁻¹¹×5⁴×5⁴
D = 5⁻¹¹⁺⁴⁺⁴
D = 5⁻³
Factoriser :
E = 3x(x-2)-(x-2)²
___ ___
Alors :
E = (x-2)(3x-x+2)
E = (x-2)(2x+2)
E = (x-2)2(x+1)
E = 2(x-2)(x+1)
F = y⁴+y²
F = y²×y² + y²
_ __
Alors :
F = y²(y²+1)
Développer :
G = z(z²-z+z)+z²
G = z(z²+0)+z²
G = z(z²)+z²
G = z³+z²
H = 1-2a(1-a)
H = 1-2a×1+2a×a
H = 1-2a+2a²
J’espère t'avoir t'aider
