# How can i simpliy this expression further? watch

Announcements
1. ln(z)+3ln(1-z)+3ln(y)+ln(1-y)+2ln(x)+2ln(1-x)

where z= exp(A)/(1+exp(A))
where y=exp(A+C)/(1+exp(A+C))
where x= exp(A+B)/(1+exp(A+B))

ln(z)+3ln(1-z)+3ln(y)+ln(1-y)+2ln(x)+2ln(1-x)

where z= exp(A)/(1+exp(A))
where y=exp(A+C)/(1+exp(A+C))
where x= exp(A+B)/(1+exp(A+B))
You can turn it all into a single ln, then substitute.
