The number of canonical expressions that can be developed over a 3-valued boolean algebra is

 A. 8 B. 16 C. 32 D. 256 Answer Report Discuss Option: D Explanation : Canonical form=SOP or POS No of min/MAX terms=23=8.  Therefore, Canonical form will have 28 have  terms. Zero term canonical forms=8C0=1.  One term canonical forms=8C1=8.  Two term canonical forms=8C2=28  Similarly total number of canonical expressions= 8C0+8C1+8C2+8C3+8C4+8C5+8C6+8C7+8C8=256 Click on Discuss to view users comments.
