3. The exclusive NOR (XNOR) function can be expressed as follows:

\[
(a \oplus b)' = \text{XNOR}(a, b) = \sum m(0, 3)
\]

This equation describes the logic function known as the exclusive NOR (XNOR). The expression \((a \oplus b)'\) represents the complement of the exclusive OR (XOR) operation between two variables \(a\) and \(b\). In Boolean algebra, this is equivalent to the XNOR operation, which outputs true only when both inputs are the same.

The summation notation \(\sum m(0, 3)\) indicates the minterms for which the XNOR function is true, specifically for the binary inputs 00 and 11. Minterms are the combinations of variables for which the function evaluates to true (or 1) in a truth table.
