Answer 1

To solve the expression \(-3^0 + 4.5\), we need to evaluate \(3^0\) first.

The correct steps are:

1. **Evaluate \(3^0\)**:
\[
3^0 = 1
\]

2. **Substitute back into the expression**:
\[
-3^0 + 4.5 = -1 + 4.5
\]

3. **Complete the addition**:
\[
-1 + 4.5 = 3.5
\]

So, the correct process is:

\[
-3^0 + 4.5 = -1 \cdot 3^0 + 4.5 = -1 \cdot 1 + 4.5 = -1 + 4.5 = 3.5
\]

Thus, the first option you provided is correct:

\[
−3^0+4.5=−1⋅3^0+4.5=−1⋅1+4.5=−1+4.5=3.5
\]
