Which of the following shows the correct process of solving
-3^0 + 4.5?
A -3^0 + 4.5 = (-3)^0 + 4.5 =
B -3^0 + 4.5 =-1 x 3^0 + 4.5 =
C -3^0 + 4. 5= -3+45=18
0-30 + 45 =-3.0 + 4.5 =
The correct process of solving -3^0 + 4.5 is A -3^0 + 4.5 = (-3)^0 + 4.5.
The correct process of solving the expression -3^0 + 4.5 is as follows:
A: -3^0 + 4.5 = (-3)^0 + 4.5
In this case, the correct answer would be A, which shows the correct process of evaluating the expression.
To correctly solve the expression -3^0 + 4.5, you need to follow the correct order of operations, which is also known as the PEMDAS rule. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's break down the options to see which one follows the correct process:
A -3^0 + 4.5 = (-3)^0 + 4.5
In this option (A), the parentheses around "-3" indicate that we need to evaluate the exponent (-3)^0 first. Any number raised to the power of 0 is always 1. So, (-3)^0 = 1.
Now, we can substitute (-3)^0 with 1:
1 + 4.5 = 5.5
Thus, option A is the correct process for solving -3^0 + 4.5.
The other options are incorrect because they don't follow the correct order of operations or make invalid calculations.
