Question

a) 4x5y5 . 5xy3

b)-3x5 . 2x3y4

c)16a3b4 : 4ab3

d) -32j4k5 : (-4jk4)

Answer 1

Resposta:

Explicação passo a passo:

A) 4.x^5.y^5 . 5.x.y^3

= 4.5.x^5.x.y^5.y^3

= 20 . x^(5+1) . y^(5+3)

= 20.x^6.y^8

b) -3.x^5 . 2.x^3.y^4

= -3.2 . x^5.x^3 . y^4

= - 6 . x^(5+3).y^4

= - 6.x^8.y^4

c)16.a^3.b^4 : 4a.b^3

= 16/4 . a^3 / a . b^4 / b^3

= 4 . a^(3-1) . b^(4-3)

= 4 . a^2 . b

d) -32j^4k^5 : (-4j.k^4)

= 32/4 . j^4 / j . k^5 / k^4

= 8 . j^(4-1) . k^(5-4)

= 8 . j^3 . k
