Question

show the full process of solving -3^0 + 4.5

Answer 1

To solve the expression \(-3^0 + 4.5\), we need to follow the order of operations and evaluate each part step by step.

1. **Evaluate \(-3^0\)**:
- The exponent \(0\) applies only to the base \(3\) (not the negative sign). Therefore, we first evaluate \(3^0\).
- Any non-zero number raised to the power of \(0\) is \(1\).
- So, \(3^0 = 1\).
- Since it was \(-3^0\), we take the negative of that result:
\[
-3^0 = -1
\]

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

3. **Perform the addition**:
- Now we add \(-1\) and \(4.5\):
\[
-1 + 4.5 = 3.5
\]

4. **Final result**:
The final result of the expression \(-3^0 + 4.5\) is:
\[
3.5
\]

Thus, \(-3^0 + 4.5 = 3.5\).
