Answer 1

Respuesta:

Explicación paso a paso:

a.

6a × 2b

= 6  × a × 2 × b

= 6 × 2 × a × b

= 12 × ab

= 12ab

b.

4ab × ( - 3a )

= 4 × a × b × ( - 3 ) × a

= 4 × ( - 3 ) × a × a × b

= - 12 × a² × b

= - 12a²b

c.

- 7a × 5b

= - 7 × a × 5 × b

= - 7 × 5 × a × b

= - 35 × ab

= - 35ab

d.

- 9x × ( - 10y )

= - 9 × x × ( - 10 ) × y

= ( - 9 ) × ( - 10 ) × x × y

= 90 × xy

= 90xy

e.

- 8y × 6x

= - 8 × y × 6 × x

= - 8 × 6 × x × y

= - 48 × xy

= - 48xy

f.

11a × ( - 4x )

= 11 × a × ( - 4 ) × x

= 11 × ( - 4 ) × a × x

= - 44 × ax

= - 44ax

g.

( 10y )²

= 10²× y²

= 10 × 10 × y²

= 100 × y²

= 100y²

h.

- y³ × ( 4x )²

= - y³ × ( 4² × x² )

= - y³ × ( 4 × 4 × x² )

= - y³ × 4 × 4 × x²

= - y³ × 16 × x²

= - 16 × y³ × x²

= - 16y³x²

i.

( 2a )³ × 6b

= 2³ × a³ × 6 × b

= 2 × 2 × 2 × 6 × a³ v b

= 48 × a³b

= 48a³b
