#### Answer

-4 $\lt$ -$\sqrt 4$.

#### Work Step by Step

To first compare the two numbers, -$\sqrt 4$ must be simplified. $\sqrt 4$ = 2. Therefore, -$\sqrt 4$ = -2. When comparing the two numbers, -4 is further left on a number line than -2. Because -4 is further away from 0 than -2, -4 is less than -2.
