To solve the expression \(-3^0 + 4.5\), it's important to tackle the exponent first. Here’s the correct process:
1. Calculate \(-3^0\). The exponentiation takes precedence:
- \(3^0\) equals \(1\).
- Therefore, \(-3^0\) equals \(-1\) (since the '-' sign is not part of the base being raised to a power).
2. Now substitute this result back into the original expression:
\[
-1 + 4.5
\]
3. Finally, perform the addition:
\[
-1 + 4.5 = 3.5
\]
So, the correct computation shows:
\[
-3^0 + 4.5 = -1 + 4.5 = 3.5
\]
Thus, the correct answer is:
**C. \(-3^0 + 4.5 = -1 \times 3^0 + 4.5 = -1 \times 1 + 4.5 = 3.5\)**.
