Đáp án:
\(\left\{ {0\,\,;\,\,1\,\,;\,\,5\,\,;\,\,6} \right\}\)
Giải thích các bước giải:
Ta có :
\(\begin{array}{l}
A\backslash B = \left\{ {0;1} \right\}\,\,;\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,B\backslash A = \left\{ {5;6} \right\}\\
\Rightarrow \left( {A\backslash B} \right) \cup \left( {B\backslash A} \right) = \left\{ {0\,\,;\,\,1\,\,;\,\,5\,\,;\,\,6} \right\}
\end{array}\)
