Question

Reduza a uma só potência. a) (–12). (–12) . (–12)²= c) { [ (m)² ]³ }5 = b) (–21)4 : (–21)³ = d) [ (x)³ . (y)5]3 =

Answer 1

Resposta:

Explicação passo-a-passo:

a) (–12). (–12) . (–12)²=

= (-12)^(1+1+2)

= (-12)^4

c) { [ (m)² ]³ }^5 =

= m^ (2.3.5)

= m ^30

b) (–21)^4 : (–21)³ =

= (-21)^(4+3)

= (-21)^7

d) [ (x)³ . (y)^5]^3 =

= (x^3)^3 . (y^5)^3

= x^9. y^15
