Question

6) Calcule as operações com monômios:

a) -3x + 2x =

b) 2ab + 3ab – 6ab =

c) 7y – 12y + 3y =

d) -5x + 2x + 8x – 10x + 3x =

e) 5 . 2x =

f) 3x . (-4x) =

g) (2x)3

=

h) 8xy : 2x =

i) 5x2

: 5x =

j) (3x2

y

3

)

2

7) Calcule as operações com polinômios:

a) (2x – 7) + (x + 8) =

b) (3x + 1) – (x – 2) =

c) (2x + 5) . (x – 2) =

d) (3x + 2y – 4) + (5x + y – 1) =​

Answer 1

Resposta:

(×-7+)+(×+8)=190×(+11)=123
