a) 5. (2x) =

b) (3x). (5x²) =

c) (3y²). (7y³) =

d) (6y5). (4xy) =

e) (8xy).(2x²y³) =

f) (9x). (3x³y³) =​

Answer 1

Resposta:

A) $=10x$

B) $=15x^3$

C) $=21y^5$

D) $=24y^6x$

E) $=16x^3y^4$

F) $=27x^4y^3$

Explicação passo a passo:

A) $5\left(2x\right)$

$=5\cdot \:2x$

$=10x$

B) $\left(3x\right)\left(5x^2\right)$

$=3\cdot \:5x^{1+2}$

$=15x^3$

C) $\left(3y^2\right)\left(7y^3\right)$

$=3\cdot \:7y^{2+3}$

$=3\cdot \:7y^5$

$=21y^5$

D) $\left(6y^5\right)\left(4xy\right)$

$=6\cdot \:4xy^{5+1}$

$=6\cdot \:4xy^6$

$=24y^6x$

E) $\left(8xy\right)\left(2x^2y^3\right)$

$=8y\cdot \:2x^{1+2}y^3$

$=8y\cdot \:2x^3y^3$

$=8\cdot \:2x^3y^{1+3}$

$=8\cdot \:2x^3y^4$

$=16x^3y^4$

F) $\left(9x\right)\left(3x^3y^3\right)$

$=9\cdot \:3x^{1+3}y^3$

$=9\cdot \:3x^{1+3}y^3$

$=27x^4y^3$

Answer 2

Resposta / Explicação passo a passo:

a) 5. ( 2 x ) = ........ 10x

5 . 2 = 10

b) ( 3 x ) . ( 5 x² ) = ........... 15x^3

3 . 5 = 15

x . x² = x³

c) ( 3 y² ) . ( 7 y³ ) = ........... 21y^5

3 . 7 = 21

y² . y³ = y^5

d) (  6 y5 ) . ( 4 x y ) = ........... 24xy^6

6 . 4 = 24

y^5 . y = y^6

e) ( 8 x y ) . ( 2 x² y³ ) = ........... 16x^3y^4

8 . 2 = 16

x . x² = x³

y . y³ = y^4

f) ( 9 x ) . ( 3 x³ y³ ) =​ ......... 27x^4y^3

9 . 3 = 27

x . x³ = x^4
