Homework SourseLet A3n Z 1 n 3 n Z B1 2 and C 12 Find A X B X C Soluti
Let, A={3n Z | -1 n 3, n Z } , B={1, 2} and C = {{1,2}}. Find A X ( B X C) .
Solution
A={-3,0,3,6,9}
BxC={(1,{1,2}),(2,{1,2})}
AX(BxC)={(-3,(1,{1,2})),(0,(1,{1,2})),(3,(1,{1,2})),(6,(1,{1,2})),(9,(1,{1,2})),(-3,(2,{1,2})),(0,(2,{1,2})),(3,(2,{1,2})),(6,(2,{1,2})),(9,(2,{1,2}))}
