Tính giá trị của biểu thức bằng cách hợp lý (nếu có thể):
\(a) \; \left| { - 3} \right| + \left| { - 2,65} \right| - \left| 0 \right| \) \(b) \;{ \left( { - 3} \right)^3}. \frac{{11}}{{45}} + { \left( { - 3} \right)^3}. \frac{4}{{45}} \)
\(c) \; \sqrt {25} . \frac{1}{{10}} + { \left( { \frac{{ - 1}}{2}} \right)^2} \) \(d) \; - \left( {23,5.5 + 19,6} \right) + 5.23,5 - \left( {6 - 19,6} \right) \)
