b) 6k⁶- 4y³ + 4y³ + 7k⁶ =

c) (2xy³) . (-4x³)=

d)(6y⁸) : (-3y²)=​

Answer 1

Explicação passo-a-passo:

a)

$\sf +8x^2-5x^5+5x^2-8x^5=(8+5)x^2-(5+8)x^5$

$\sf =13x^2-13x^5$

b)

$\sf 6k^6-4y^3+4y^3+7k^6=(6+7)k^6-(4-4)y^3$

$\sf =13k^6$

c) $\sf (2xy^3)\cdot(-4x^3)=-8x^4y^3$

d) $\sf (6y^8)\div(-3y^2)=-2y^6$

Answer 2

Oie, Td Bom?!

a)

$= 8x {}^{2} - 5x {}^{5} + 5x {}^{2} - 8x {}^{5} \\ = 13x {}^{2} - 5x {}^{5} - 8x {}^{5} \\ = 13x {}^{2} - 13x {}^{5}$

b)

$= 6k {}^{6} - 4y {}^{3} + 4y {}^{3} + 7k {}^{6} \\ = 6k {}^{6} + 7k {}^{6} \\ = 13k {}^{6}$

c)

$= (2xy {}^{3} ) \: . \: ( - 4x {}^{3} ) \\ = - 2xy {}^{3} \: . \: 4x {}^{3} \\ = - 8x {}^{4} y {}^{3}$

d)

$= (6y {}^{8} ) \div ( - 3y {}^{2} ) \\ = - 6y {}^{8} \div (3y {}^{2} ) \\ = - 2y {}^{6}$
