exercício proposto
calcule:​

Answer 1

Resposta:

a)-10x²

b)6y³

c)20a³x⁵

d)-x

e)-18xy

f)30x²y²

Explicação passo-a-passo:

a)(+5)×(-2)=-10

(x¹) ×( x¹)=x²

-10x²

b)(-2)×(-3)=+6

(y) ×( y²) = y³

6y³

c)(+4)×(+5)=+20

(ax²) × (a²x³) = a³x⁵

20a³x⁵

d)(+x²)×(-x)= -x (subtrai os expoentes )

e)(-6)×(+3)= -18

(x) × (y) = xy

-18xy

f)(-5)×(-2)×(+3)=+30

(x)× (xy)× (y)= x²y²

30x²y²
