To solve the expression \(-3^0 + 4.5\), we need to evaluate the components carefully.
- First, calculate \(3^0\). Any non-zero number raised to the power of 0 is \(1\), so \(3^0 = 1\).
- Therefore, \(-3^0\) is \(-1\) (because it is considered as leading \(-3\) raised to the power \(0\)).
- Now substitute back into the expression: \(-1 + 4.5\).
- Now, calculate \(-1 + 4.5 = 3.5\).
So the correct process from the provided responses is:
−3^0 + 4.5 = −1 ⋅ 3^0 + 4.5 = −1 ⋅ 1 + 4.5 = −1 + 4.5 = 3.5
This matches the third option provided.
