−3 superscript 0+4.5=(−3) superscript 0+4.5=1+4.5=5.5
negative 3 superscript 0 baseline plus 4.5 equals left parenthesis negative 3 right parenthesis superscript 0 baseline plus 4.5 equals 1 plus 4.5 equals 5.5

−3 superscript 0+4.5=−1⋅3 superscript 0+4.5=−1⋅1+4.5=−1+4.5=3.5
negative 3 superscript 0 baseline plus 4.5 equals negative 1 times 3 superscript 0 baseline plus 4.5 equals negative 1 dot 1 plus 4.5 equals negative 1 plus 4.5 equals 3.5

−3 superscript 0+4.5=−3+4.5=1.5
negative 3 superscript 0 baseline plus 4.5 equals negative 3 plus 4.5 equals 1.5

−3 superscript 0+4.5=−3⋅0+4.5=0+4.5=4.5

Answer 1

To solve \(-3^0 + 4.5\), we follow these steps:

1. Recall that any non-zero number raised to the power of 0 is equal to 1. Therefore, \(-3^0\) equals 1, as the base (-3) is non-zero.
2. The expression can be simplified as follows:
\[
-3^0 + 4.5 = 1 + 4.5 = 5.5
\]

So the correct process for solving \(-3^0 + 4.5\) is:

**−3 superscript 0 + 4.5 = (−3) superscript 0 + 4.5 = 1 + 4.5 = 5.5.**

This corresponds to the first response you provided.
