How would you implement the expression A' + B?

Input A to a NOT gate, then its output and B to an OR gate.

Inputs A and B to an OR gate, then the output to a NOT gate.

Input A to a NOT gate, then its output and B to an AND gate.

Inputs A and B to an AND gate, then the output to a NOT gate.

A circuit implementing A' · B' would use:

Two NOT gates and one AND gate.

One NOT gate and two AND gates.

The expression A + B + C' is implemented with:

One NOT gate and one 3-input OR gate.

Three NOT gates and one 3-input OR gate.
