7-124.

Differentiate the following equations.

1. $f ( x ) = \frac { \operatorname { tan } x } { e ^ { - x } }$

You could use the Quotient Rule, or rewrite this fraction without the negative exponent in the denominator.

1. $y^3 − 3xy = 3^y$

1. $g(t) =\operatorname{ln}(t)\sqrt { t }$

Before differentiating, rewrite g(t) with a fractional exponent.
