117,115,13,14
117,116,12,14
116,115,114,113,12,13
117,14
115,114,113,13
116,114,113,12
If \(U\) \(=\) 117,116,115,114,113,12,13,14, \(M\) \(=\) 115,114,113,13 and \(N\) \(=\)116,114,113,12, then verify \((M\cup N)^{\prime}\) \(=\) \(M^{\prime} \cap N^{\prime}\).
 
\(M \cup N\) \(=\)
,  \((M \cup N)^{\prime}\) \(=\)
 
\(M^{\prime}\) \(=\)
,  \(N^{\prime}\) \(=\)
 
\(M^{\prime} \cap N^{\prime}\) \(=\)
