To solve the expression \( -30 + 4.5 \), we first interpret \( -30 \) as \( -3 \cdot 10 \), but in this case, the most straightforward understanding is simply viewing it as a negative number.

The correct interpretation of \( -30 \) is straightforward as just \( -30 \).

Let's compute:

\[ -30 + 4.5 = -30 + 4.5 \]

To do the math step-by-step:

  1. Start with \( -30 \).
  2. Adding \( 4.5 \) would mean moving up \( 4.5 \) on the number line from \( -30 \).
  3. The result can be found as follows:

\[ -30 + 4.5 = -25.5 \]

None of the options you provided arrive at this correct computation. However, if I had to choose an option based on how they are expressed in your question, I would emphasize the understanding of operations with different forms of negative or positive numbers rather than selecting any option as correct because they do not seem to correctly reflect the computation of \( -30 + 4.5 \).

If you meant \( -3^0 \) to be calculated instead of \( -30 \), please let me know! The calculation of \( -3^0 \) would yield a different result as \( 1 + 4.5 = 5.5 \).

Could you clarify which specific expression you intended to analyze?
