Which of the following shows the correct process of solving −3^0+4.5?(1 point)
The correct process of solving −3^0+4.5 is as follows:
First, we evaluate -3^0. According to the order of operations (PEMDAS/BODMAS), exponentiation is performed before addition.
Since any number (except 0) raised to the power of 0 equals 1, we have -3^0 = -1.
Next, we add 4.5 to -1, resulting in -1 + 4.5 = 3.5.
Therefore, the correct process of solving −3^0+4.5 is -1 + 4.5 = 3.5.

To solve the expression −3^0 + 4.5, follow these steps:
Step 1: Evaluate the power: -3^0
-3^0 means -3 raised to the power of 0. Any number raised to the power of 0 equals 1. So, -3^0 equals 1.
Step 2: Perform addition: -3^0 + 4.5
Now, substitute the evaluated value of -3^0 into the expression: 1 + 4.5.
Step 3: Calculate the sum:
1 + 4.5 = 5.5.
Therefore, the correct process to solve the expression is:
-3^0 + 4.5 = 5.5.
To solve the given expression −3^0+4.5, we need to follow the correct order of operations, which is commonly referred to as PEMDAS (Parentheses, Exponents, Multiplication and Division [from left to right], and Addition and Subtraction [from left to right]).
1. Evaluate the Exponent:
The exponent in this expression is 0, which means any number raised to the power of 0 is equal to 1. Therefore, −3^0 simplifies to −3^0 = −1.
2. Perform the Addition:
Next, we can add −1 to 4.5.
−1 + 4.5 = 3.5.
So, the correct process of solving the expression −3^0+4.5 is to first evaluate the exponent (which simplifies to −1) and then perform the addition. The final answer is 3.5.
