Answer 1

a)

-3*4*(-3,25)*(-3)=-12*9,75=-117

 

b)

-2,8a*40ax*(-1)*a^2=112a^2x*a^2=112a^4x

 

c)

(-6y)*(-y)*(-0,2)*y=6y^3*(-0,2)=-1,2y^3

 

d)

2,5*x*(-1,8)*(-10)xy=-4,5x*(-10)xy=45x^2y

 

e)

-4*(-x)*(-y)*(-y)*x*y^2=4x*y*y^2*x=4x^2y^4

 

f)

1/3a*a*(-b)*a*(-b)*1/3=1/9a^3b^2

Answer 2

a)         1                   13

-3·4·(-3--)·(-3)=36·(- --)=- 9·13=-117

              4                    4

b)

-2,8a·40ax·(-1)a²=112a⁴x

c)

(-6y)·(-y)·(-0,2)·y=6y²·(-0,2)·y=-1,2y³

d)
