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 \(-3^0\)**: The expression \( -3^0 \) can be evaluated as follows:
- Any non-zero number raised to the power of zero is \(1\).
- So, \( -3^0 = -1 \).

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

3. **Calculating the result**:
\[
-1 + 4.5 = 3.5
\]

So, the correct process to solve the expression is:
- The correct answer is \( -3^0 + 4.5 = -1 + 4.5 = 3.5 \).

Now, let's evaluate the options provided:

1. **Option 1**: Incorrect. The steps contain errors.
2. **Option 2**: Incorrect. The evaluation of \( -3^0 \) is miscalculated.
3. **Option 3**: Incorrect. The evaluation does not follow the correct exponent rule.
4. **Option 4**: Incorrect. Misapplies rules and calculations.

None of the options correctly show the steps. The right calculation is \( -1 + 4.5 = 3.5 \).
