Giải thích các bước giải:
Ta có:
\(\begin{array}{l}
a,\\
A \cap R = \left( { - 4;5} \right]\\
A \cup R = R\\
A\backslash R = \emptyset \\
R\backslash A = \left( { - \infty ; - 4} \right] \cup \left( {5; + \infty } \right)\\
b,\\
C \cap B = \left( {0;6} \right)\\
C \cup B = \left[ { - 3; + \infty } \right)\\
C\backslash B = \left[ {6; + \infty } \right)\\
B\backslash C = \left[ { - 3;0} \right]\\
c,\\
A \cap B \cap C = \left( {0;5} \right]\\
A \cup B \cup C = \left( { - 4; + \infty } \right)\\
d,\\
\left( {A \cup B} \right) \cap C = \left( {0;6} \right)\\
\left( {A \cap B} \right) \cup C = \left[ { - 3; + \infty } \right)\\
\left( {A \cup B} \right)\backslash C = \left( { - 4;0} \right]\\
\left( {A \cap B} \right)\backslash C = \left[ { - 3;0} \right]
\end{array}\)
