Answer 1

Resposta:

0.

Explicação passo a passo:

$\lim_{x \to \ 8} \frac{x^{4}-8x^{3} }{2+5x^{7} }$

Calculando o limite temos:

$\frac{8^{4}(-8)8^{3}}{2+(5)8^{7} }$

$\Rightarrow\frac{8^{4}-8^{4}}{2+(5)8^{7} }$

$\Rightarrow\ 0$

$\therefore\lim_{x \to \ 8} \frac{x^{4}-8x^{3} }{2+5x^{7} } \iff 0$
