shows the correct process of solving −3^0+4.5
To solve the expression −3^0 + 4.5, we follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Since we don't have parentheses or multiplication/division operations, we focus on the exponentiation (Exponents).
Now, the exponent rule states that any number raised to the power of 0 is equal to 1. So, −3^0 becomes −3^0 = −1.
Now, we can rewrite the expression as −1 + 4.5.
Finally, adding -1 and 4.5, we get:
−1 + 4.5 = 3.5.
Therefore, the correct value of the expression −3^0 + 4.5 is 3.5.
To solve the expression −3^0 + 4.5, follow these steps:
Step 1: Evaluate the exponent.
Since any number raised to the power of 0 is equal to 1, −3^0 becomes −3^1, which is still −3.
Step 2: Calculate the addition.
Now, the expression becomes −3 + 4.5.
Step 3: Perform the addition operation.
−3 + 4.5 equals 1.5.
Therefore, the correct process of solving −3^0 + 4.5 is as follows:
−3^0 + 4.5 = −3 + 4.5 = 1.5.
