Question

Which of5 the following shows the correct process of solving -3^0 + 4.5

-3^0 + 4.5 = - 1.3^0 + 4.5 = - 1.1 + 4.5 =-1+ 4.5 = 3.5

-3^0 + 4.5 = -3^0 + 4.5 = 1 + 4.5 = 1 + 4.5 = 5.5

-3^0 + 4.5 = -3+4.5=1.5

-3^0 + 4.5 = -3.0+4.5=0+4.5=4.4

Answer 1

Let's break down the expression \(-3^0 + 4.5\) step by step.

1. **Evaluate \(-3^0\)**:
- Any number (except zero) raised to the power of 0 is 1.
- Therefore, \(-3^0 = -1\).

2. **Combine with \(4.5\)**:
- Now we have \(-1 + 4.5\).

3. **Calculate**:
- \(-1 + 4.5 = 3.5\).

Now, let’s review the options given:

1. **-3^0 + 4.5 = -1.3^0 + 4.5 = -1.1 + 4.5 = -1 + 4.5 = 3.5**
- The first part is incorrect because it incorrectly states \(-1.3^0\) instead of correctly calculating \(-3^0\). However, the final result \(3.5\) is correct.

2. **-3^0 + 4.5 = -3^0 + 4.5 = 1 + 4.5 = 1 + 4.5 = 5.5**
- This is incorrect because it mistakenly states \(-3^0 = 1\) instead of \(-3^0 = -1\).

3. **-3^0 + 4.5 = -3 + 4.5 = 1.5**
- This is incorrect because it incorrectly replaces \(-3^0\) with \(-3\).

4. **-3^0 + 4.5 = -3.0 + 4.5 = 0 + 4.5 = 4.4**
- This is incorrect, as it mistakenly evaluates \(-3^0\) as \(-3.0\).

Thus, while the first option has a calculation error in steps leading to \(3.5\), it is the only one that arrives at the correct final answer, which is \(3.5\).

**The correct choice based on the final result is the first option, albeit with an initial error.**
