• commutative

• distributive

• identity

Sneha and Avani are working on a project where they need a logic circuit that provides a HIGH output when both of their inputs are HIGH or both are LOW. Which type of logic circuit should they use?

Aditi is studying digital logic and comes across De Morgan’s theorem. She learns that it states that

• (AB)' = A + B

• (A + B)' = AB

• (AB)' = A' + B

• (A + B)' = A'B'

Tisha is working on a project where she needs to simplify a boolean function. She finds that the function A + BC is a reduced form of another expression. Can you help her identify which one it is?
