Answer 1

Respuesta:

Explicación paso a paso:

11. a. No

-3x⁴.(-2x³)²=-3x⁴.(4x⁶)=-12x¹⁰

b. No es cierta

(x+3)³=x³+9x²+27x+27

12. a.4x⁶.(-6x²)=-24x⁸

b.1/2 x.4x³= 2x⁴

c.-5x².3x⁷= - 15x⁹

d.2/3 x.(-2x).3x⁴= -4/3 x². 3x⁴ =-4x⁶

13.a.-3x².(2x-1/9x⁴+2)= (-3x².2x)-(-3x².1/9 x⁴)+(-3x².2)=-6x⁴+1/3 x⁶-6x²

=1/3 x⁶-6x⁴-6x²

b.(-x³+2x²-4x+1).(-x) =(-x³.-x)+(2x².-x)-(4x.-x)+(1.-x)= x⁴-2x³+x

c.2/3 x.(27x²-3x+9)= (2/3x .27x²)-(2/3 x.3x)+(2/3 x.9)= 18x³-2x²+6x

14. a. (-3x+1).(3x+1) = -9x²+3x-3x+1 = -9x²+1

c.(2x³-4).(2x³-4)= 4x⁶-8x³-8x³+16 =4x⁶-16x³+16

d. (-x²+3).(-x²+3)=x⁴-3x²-3x²+9 =x⁴-6x²+9
