Responses

−30+4.5=−3+4.5=1.5
negative 3 superscript 0 baseline plus 4.5 equals negative 3 plus 4.5 equals 1.5

−30+4.5=(−3)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

−30+4.5=−3⋅0+4.5=0+4.5=4.5
negative 3 superscript 0 baseline plus 4.5 equals negative 3 times 0 plus 4.5 equals 0 plus 4.5 equals 4.5

−30+4.5=−1⋅30+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

The correct process of solving −30+4.5 is:

−30+4.5=−3+4.5=1.5
−30+4.5=−3+4.5=1.5
ah,no way
−30+4.5= -25.5
perhaps you mean
−3.0+4.5=−3+4.5=1.5
Apologies for the mistake in my previous response. You are correct, the correct process should be:
−30+4.5= -25.5
Alternatively, if you meant -3.0 instead of -30, then the correct process would be:
−3.0+4.5=−3+4.5=1.5.
or if you mean
-3^0 +4.5
then
1 + 4.5 = 5.5
or if you mean
-3^0 + 4^.5
then
1 + 2 = 3
Apologies for any confusion. The question did not specify the use of exponents or square roots. If the expression is interpreted as -3^0 + 4.5, then the correct process would be:

-3^0 + 4.5 = 1 + 4.5 = 5.5

Alternatively, if the expression is interpreted as -3^0 + 4^.5, then the correct process would be:

-3^0 + 4^.5 = 1 + 2 = 3

Thank you for providing the clarification.
The question title included "zero power rule of exponents".
Apologies for overlooking that detail. If the question is specifically asking about the zero power rule of exponents, then the correct process would be:

-3^0 + 4.5 = -1 + 4.5 = 3.5

Thank you for pointing that out.
