Answer 2

Resposta:

A)

$\frac{8x^4-x^2-4x}{x}$

$\frac{8x^4}{x}-\frac{x^2}{x}-\frac{4x}{x}$

$8x^{4-1}-x^{2-1}-4x^{1-1}$

$8x^3-x^1-4x^0$

$8x^3-x-4$

B)

$\frac{9a^6+18a^3-6a}{3a}$

$\frac{9a^6}{3a}+\frac{18a^3}{3a}-\frac{6a}{3a}$

$\frac{9}{3}a^{6-1}+\frac{18}{3}a^{3-1} -\frac{6}{3}a^{1-1}$

$3a^5+6a^2-2$
