What is the complement of the expression $F=(x^{\text{'}}+y+z^{\text{'}})(x+y^{\text{'}})(x+z)?$

Express the following function as a sum of minterms and as a product of maxterms

$F(A,B,C,D)=B^{\text{'}}D+A^{\text{'}}D+BD$

Express the complement of the following functions in sum$-$of$-$minterms form

a$)F(A,B,C,D)=(2,4,7,10,12,14)$

b$)F(x,y,z)=(3,5,7)$
