The result is $- \frac{9}{4}$ $-9/4$ .

You can distribute the radical onto each of the fraction parts, then simplify each one:

$= - \sqrt{\frac{81}{16}}$ $color(white)=-sqrt(81/16)$

$= - \frac{\sqrt{81}}{\sqrt{16}}$ $=-sqrt81/sqrt16$

$= - \frac{\sqrt{9^{2}}}{\sqrt{4^{2}}}$ $=-sqrt(9^2)/sqrt(4^2)$

$= - \frac{9}{4}$ $=-9/4$

That's the result. Hope this helped!
