Answer 1

To solve the expression -30 + 4.5, we first need to clarify that -30 is the same as -3 * 10. However, it seems there's a misunderstanding in the choices regarding exponentiation.

Let's break down the calculation correctly:

-30 + 4.5 can be computed directly:

1. Take -30.
2. Add 4.5 to it:

\(-30 + 4.5 = -25.5\)

None of the given options provided the correct final result. However, if we are to strictly choose the nearest correct approach, the one that represents the operation without erroneous steps would ideally demonstrate how to handle the addition of a negative and a positive number directly. Therefore, in the context of your choices, if we are required to select one but note there are issues, we should look for a procedure aligning more with simple arithmetic.

Overall, the accurate result of the original expression is:

-30 + 4.5 = -25.5.

Since none of the options show this correctly, the problem would need to be revisited for potential misinterpretation of the notation.
