Determine the following limit$,$ using $$ or $-$ when appropriate, or state that it does not exist.

$\underset{x0}{lim}\frac{x^{5}9x^4}{x^4}$

Simplify the expression inside the limit$,$ if possible. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A$.\underset{x0}{lim}\frac{x^{5}9x^4}{x^4}=\underset{x0}{lim}((x9))$

The expression inside the limit cannot be simplified

Now, evaluate the limit$.$ Select the correct choice below and, if necessary, till in the answer box to complete your choice

A$.\underset{x0}{lim}\frac{x^{5}9x^4}{x^4}=($Type an integer or a simplified fraction$)$

e$.$ The limit does not exist and is neither $$ nor $-$
