Question

se da miltimea C={x€N|x<11}. aflati ( C intersectat cu D4))\(C\D6)

Answer 1

C={0,1,2,3,4,5,6,7,8,9,10}
C intersectat cu D4={0,1,2,3,4,5,6,7,8,9,10} intersectat cu {0,1,2,4}={0,1,2,4}
C\D6={0,1,2,3,4,5,6,7,8,9,10}\{0,1,2,3,6}={7,8,9,10}

(C intersrctat cu D4)\(C\D6)= {0,1,2,4}\{7,8,9,10}={0,1,2,4}
