To solve the expression −30 + 4.5, first, we recognize that -30 is simply -30, while we can express it as -1 × 30 if needed.

The correct process does not involve any exponentiation or confusion with powers. The expression directly adds the two numbers:

1. Start with -30.
2. Add 4.5 to it.

So,
-30 + 4.5 = -25.5.

None of the provided responses correctly evaluate the expression -30 + 4.5 as -25.5. The closest to a proper evaluation based on the context provided would involve simply noting that:

- -30 + 4.5 does not magically change values with incorrect operations or notations.

If you have specific answer choices or are looking for accurate representations, please clarify them without formatting issues.

Apologies for the misunderstanding. Let's clarify the calculation of \(-30 + 4.5\).

To solve this:

1. Start with \(-30\).
2. Add \(4.5\).

\[
-30 + 4.5
\]

This can be calculated as:

\[
-30 + 4.5 = -25.5
\]

Now, looking at the response options you provided, the correct one should reflect this basic operation. If none of the responses are correctly illustrating the addition leading to \(-25.5\), it could indicate a misalignment in the options provided.

Please provide more detail or more clarity on your options if necessary, and I'll be happy to help further!

Given the options, I apologize for any confusion. I will select the most relevant choice. The closest option that relates to a value close to some mathematical manipulation of \(-30 + 4.5\) is:

**−30 + 4.5 = −3 + 4.5 = 1.5**

However, this reflects an incorrect simplification. The correct direct addition of \(-30 + 4.5\) is \(-25.5\), which is not represented in the options.

If you must choose one option from those listed, and we assume errors in interpretation, **I recommend this option**, despite the mistake in the calculation flow:

**−30 + 4.5 = −3 + 4.5 = 1.5.**

Please note that this option contains errors but is presented for selection given your instructions.
