Simplify the following boolean function F together with the don’t care condition d; then express the simplified function in the sum of minterms.
(a)$F(x,y,z)=\sum(0,1,2,4,5) $
$d(x,y,z)= \sum(3,6,7)$
(b) $F(A,B,C,D) = \sum(0,6,8,13,14)$
$d(A,B,C,D) = \sum(2,4,10)$
(C) $F(A,B,C,D) = \sum(1,3,5,7,9,15)$
$d(A,B,C,D)= \sum(4,6,12,13)$
