Test by Bikram | Mock GATE | Test 4 | Question: 29
The value of $ f + g $ in the above circuit is: $x{}'y + x{}'z + yz + yz{}'$ $x{}'y + x{}'z + y{}'z'+ y{}'z$ $x{}'y + y{}'z{}' + yz + x{}'z$ $xy + y{}'z{}'+ x{}'z + yz$
The value of $ f + g $ in the above circuit is:$x{}'y + x{}'z + yz + yz{}'$$x{}'y + x{}'z + y{}'z'+ y{}'z$$x{}'y + y{}'z{}' + yz + x{}'z$$xy + y{}'z{}'+ x{}'z + yz$
