8-94.

Multiple Choice: If $f ( x ) = \frac { e ^ { \sqrt { x } } } { \sqrt { x } }$, then $f^\prime(x) =$

1. $0$

1. $1$

1. $e ^ { \sqrt { x } }$

1. $\frac { e ^ { \sqrt { x } } } { x }$

1. $\frac { e ^ { \sqrt { x } } ( x - \sqrt { x } ) } { 2 x ^ { 2 } }$

Use the Quotient Rule, or rewrite $f(x)$ with a negative exponent and then use the Product Rule.
