2^6/(11/5 - 1/30 - 3/10 + 2/15)^4 - (- 1/2 - 7/4)^2=
=2^6/2^4 - (- 9/4)^2=
=64/16 - 81/16=
=- 17/16
N.B
11/5 - 1/30 - 3/10 + 2/15 = (11·6 - 1 - 3·3 + 2·2)/30=
=60/30 = 2

$\small 2^6÷\left(\dfrac{11}{5}-\dfrac{1}{30}-\dfrac{3}{10}+\dfrac{2}{15}\right)^4-\left(-\dfrac{1}{2}-\dfrac{7}{4}\right)^2 =$
$\small = 2^6÷\left(\dfrac{66-1-9+4}{30}\right)^4-\left(\dfrac{-2-7}{4}\right)^2 =$
$\small = 2^6÷\left(\dfrac{\cancel{60}^2}{\cancel{30}_1}\right)^4-\left(-\dfrac{9}{4}\right)^2 =$
$\small = 2^6÷2^4-\dfrac{81}{16} =$
$\small = 2^{6-4}-\dfrac{81}{16} =$
$\small = 2^2-\dfrac{81}{16} =$
$\small = 4-\dfrac{81}{16} =$
$\small = \dfrac{64-81}{16} =$
$\small = -\dfrac{17}{16} $
