Question

3) Determine os seguintes quocientes: a) (– 8x ) : ( – 2x ) b) (– 14x³ ) : ( + 7x² ) c) (– 10x³y ) : ( + 2x ) d) ( + 6x³y ) : ( – 2xy ) e) ( + 35x³ ) : ( + 5x )

Answer 1

Resposta:

a)4

b)-2x

c)=5x^3y

d)-3x^2

e)7x^2

Explicação passo-a-passo:

a)(– 8x ) : ( – 2x )

-a/-b = a/b

-8/-2 = 8/2

8x/2x = 4x/x

=4

b)(– 14x³ ) : ( + 7x² )

-a/+b = -a/b

14x^3/7x^2

14/7 = 2

2x^3/x^2

x^a/x^b = x^a-b

2x^3-2

c)(– 10x³y ) : ( + 2x )

-a/+b = -a/b

-10x^3y/2x

5x^3y/2x

=5x^3y

d)( + 6x³y ) : ( – 2xy )

-6x^3y/2xy

3x^3y/xy = 3x^2y/y

=-3x^2

e)( + 35x³ ) : ( + 5x )

35/5=7

7x^3/x

=7x^2
