This is ambiguous. I will take the problem as it is written. (As it happens there is no difference in the final result between this and the other likely interpretation.)

$\displaystyle (4 - \sqrt{16}) + \frac{-7 - 20}{-2(1 - 4)^2}$

$\displaystyle (4 - 4) + \frac{-27}{-2(-3)^2}$

$\displaystyle 0 + \frac{-27}{-2 \cdot 9}$

$\displaystyle \frac{-3}{-2}$

$\displaystyle \frac{3}{2}$
