a) X = ABC + A\C\
Answer :
= C (AB +A\)
= C (A\+B)
= A\C+BC
b) Y = (Q + R) (Q\+R\)
Answer :
= QQ\ + QR\ + Q\R + RR\
= QR\ + Q\R
c) W = ABC + AB\C + A\
Answer :
= AC (B + B\) + A\
= AC + A\
d) Q = R\S\T\ (R+S+T)\
Answer :
= (RST)\ (R+S+T)\
= (RST)\+(RST)\+(RST)\
= (RST)\
e) X = A\B\C\ + A\BC + ABC + AB\C\ + AB\C
Answer :
= A\B\C\ + AB\C\ + A\BC + ABC + AB\C
= B\C\ (A\+A) + BC (A\+A) + AB\C
= B\C\ + BC +AB\C
= B\C\ + C (B + AB\)
= B\C\ + C (B + A)
= B\C\ + BC + AC
f) Z = (B+C\) (B\+C) A\\+B\+C\\
Answer :
= BB\ + BC + B\C\ + C\C + AB\C
= BC + B\C\ + AB\C
= BC + B\ (C\+AC)
= BC + B\ (C\+A)
= BC + B\C\ + AB\
g) Y = (C+D)\ + A\CD\ + AB\C\ + A\B\CD + ACD\
Answer :
= C\D\ + A\CD\ + ACD\ + AB\C\ + A\B\CD
= C\D\ + CD\ (A\ + A) + AB\C\ + A\B\CD
= C\D\ + CD\ + AB\C\ + A\B\CD
= D\ (C\+C) + AB\C\ + A\B\CD
= D\ + AB\C\ + A\B\CD
= D\ + B\ (AC\+A\CD)
h) X = AB (C\D)\ + A\BD + B\C\D\
Answer :
= AB (CD\) + A\BD + B\C\D\
= ABC + ABD\ + A\BD + B\C\D\
= ABC + A\BD + ABD\ + B\C\D\
= B (AC+A\D) + D\ (AB+B\C\)
