Даны векторы \(\overrightarrow{m}=-4\overrightarrow{i}+2\overrightarrow{j}-3\overrightarrow{k}\) и \(\overrightarrow{n}=3\overrightarrow{i}-8\overrightarrow{j}+4\overrightarrow{k}\)

\(\overrightarrow{m} \cdot \overrightarrow{n}=\) [ ]

\(\overrightarrow{m} \cdot \overrightarrow{i}=\) [ ]

\(\overrightarrow{n} \cdot \overrightarrow{j}=\) [ ]

\((\overrightarrow{m} + \overrightarrow{n} ) \cdot \overrightarrow{k}=\) [ ]
