To simplify the expression \( 3^2 - 4 \) over 5, we can follow the order of operations (often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).
1. **Calculate the exponent:**
\[
3^2 = 9
\]
2. **Subtract 4 from 9:**
\[
9 - 4 = 5
\]
3. **Now divide by 5:**
\[
\frac{5}{5} = 1
\]
So, the simplified expression is:
\[
\boxed{1}
\]
