What makes you think that one is wrong?

What makes you think that one is wrong?

In Solution 1 , F=

In Solution 2 ,

Which F is correct ?

Do they give different answers? truth tables?
Perhaps one simply has redundant connections.
Maybe you need a minimal one in some form, or perhaps it does not matter.
.
If for example, using normal logic rules, you could show that your upper table were able to be logically reduced to the Karnaugh map version, then you'd have to conclude they are equivalent.

for example the lines
a . b . c
and
a . b . c\
might reduce.

In solution one you have these partial expressions:
a * /b *c + a * b * c
Compare this to solution 2's partial expression:
a * c

The same comparison make for
1) a * b * /c + a * b * c
vs.
2) a * b

Note: /a shall indicate NOT(a), the negation, as I cannot create an overline here.

Is there a difference in the result? If so, which. If not, why not?
