bonjour
c =2 ¹⁴ * 5 ⁷ sur 2 ¹¹ * 5 ⁶
c = 2 ³ * 5
b = 2 ⁻¹⁵ * 3 ⁵ sur 3 ⁸ * 2 ⁶
b = 2 ⁻²¹ * 3 ⁻³
d = - 12 a + 20 + 6 a² - 14 a = 6 a² - 26 a + 20
e = - 10 a² + 6 a + 3 a + 15 = - 10 a² + 9 a + 15
F = 21 b - 7 b² - ( - 18 b² + 9 b) = 21 b - 7 b² + 18 b² - 9 b
= 11 b² + 12 b
G = 8 a² - 40 a - 15 a + 12 = 8 a² - 55 a + 12
H = x² - 8 x + 2 - 4 x² - 5 x + 15 = - 3 x² - 13 x + 17
a = 2.5 ⁶ * 0.4 ⁶ = 1 ⁶ = 1
b = - 1 ⁷ * ( -1) ³ = - 1*-1 = 1
c = 3 * ( 20)³ = 24 000
d = 16 + 25*4 = 16 + 100 = 116
e = 3 x ( 11 + 16) = 3*27 = 81
F = 81 * 11 + 8 = 899
A = 4 ⁹ * 5 ⁻⁵ = 262144 * 0.00032 = 83.88608 = 8.388 608 * 10 ⁶
B = 2 ⁶ x 6 ⁻⁶ sur 6 ⁷ x 2 ³ = 2 ³ x 6 ⁻¹³ = 8 * 6⁻¹³ = 6.12524877 x 10 ⁻¹⁰
a = 4 x² ( x - 6 x ³)
b = 2 xy ( y + 4 + x)
c = ( x + 2) ( 4 x + 3 - 2 x - 7)
c = ( x + 2) ( 2 x - 4)
