Answer 1

Respuesta:

A=x^3

B=x^5

C: (2x^4)(3x^2) =x^6

D: (-2x^7)(5x^-2) = 10x^5

E: (6)(3x-2) = 18x-12

F: (9)(6x-5) =54x-45

G: (-3)(2x-7) =-6x +21

H: (5)(x-2) = 5x-10

I: (-2)(3x-9) =-6x+18

J: (9)(6x-5) = 54x-45

K: (x)(x-2) = x^2-2x

L: (-2x)(3x-9) = -6x^2+18

M: (9x^2)(6x-5) =54x^3-45x^2

N: (5x)(x^2+x-2) = 5x^3+5x^2-10x

O: (3x^2-7xx1)(-4)(x^5) = 16x^7

P: (-2x^2)(3x^2-9x^2+7x+1) = -2x^2(-6x^2+7x+1)

Q: (9x^6)(-5x^4-10x^3-3x^2-x+3) = -45x^6-90x^5-27x^4-9x^3+27x^2

Explicación:

D= -2x^7 * 5x^-2

2*5*1/x^2 x^7

-1*2x^7*5)/x^2

10x^7-2

-10x^5

E= 6*3x-6*2= 18x-12

F= 9*6x-9*5= 54x-45

G=-3*2x-(-3)*7= 6x+21

H=5x-5*2= 5x-10

I= -2*3x+2*9= -6x+18

J= 9*6x-9*5= 54x-45

K= xx-x*2=xx-2x=xx=x^2=x^2_2x

L=-2x*3x-(-2x)*9= -2x*3x+2*9x=-6x^2+18

M=(9x^2)*6x-(9x^2)*5=

6x(9x^2)-5(9x^2)= 54x^3-44x^2

N= 5x^2x+5xx-5*2x= 5x^3+5x^2-10x

o= -(3x^2-7xx*1)*4x^5

-4x^5(3x^2-7x^2

-4x^5(-4x^2)

16x^2+5

16x^7

P= -2x^2(-6x^2+7x+1

Q=-5x^4(9x^2)-10x^3(9x^2)-x(9x^2)+3(9x^2)= -45x^6-90x^5-27x^4-9x^3+27x^2
