Thực hiện phép tính: h) 2^ 3 + 3 ⋅ ( − 1/ 2 ) 2 − 2^ 2 ⋅ 4 + [ ( − 2 ^) 2 : 1 /2 ] ⋅ 8 ;

h) \({2^3} + 3.{\left( { - \frac{1}{2}} \right)^2} - {2^2}.4 + \left[ {{{\left( { - 2} \right)}^2}:\frac{1}{2}} \right].8\)         

\( = 8 + \frac{3}{4} - 4.4 + \left( {4:\frac{1}{2}} \right).8\)

\( = \frac{{35}}{4} - 16 + 64 = \frac{{227}}{4}\);
