How many possible minterms are there for the
variables in each expression listed below?
___ a.
AC+A+AC+C
___d.
F+AB+FAB+BA+A
___ b.
X+YZ+XY+AXYB+Z+B
___ e.
D+AC+BD
___ c.
LM+Z+CLM+MZ+MLZ

a.
4 (22)
14.
On a Veitch diagram, there is one square for
b.
32 (25)
each minterm.
c.
16 (24)
For example:
d.
8 (23)
For a two-variable expression, there are four
e.
16 (24)
minterms (22); thus, a four-square Veitch
f.
32 (25)
diagram is required.

For a three-variable expression, there are
eight minterms (23); thus, an eight-square
Veitch diagram is required.
