Which of the following shows the correct process of solving -3^0 + 4.5? (1 point)
3^0 + 4.5 =-3 + 4.5 = 1.5
3^0 + 4.5 =-1-3^0 + 4.5 = -1-1 + 4.5 =-1 + 4.5 = 3.5
3^0+4.5=(-3)^0 +45=1+45= 5.5
3^0 + 4.5=-3•0 + 4.5=0 + 4.5 = 4.5
The correct process of solving -3^0 + 4.5 is:
3^0 + 4.5 = 1 + 4.5 = 5.5
Which of the following is an equivalent expression to 7/(-3.5)^0+ 4.9 when applying the Zero Power Rule? (1 point)
7/5.3+1.9
7/1+4.9
7/0+4.9
7/5.3^0 + 36
The correct equivalent expression when applying the Zero Power Rule is:
7/1 + 4.9
The correct process of solving -3^0 + 4.5 is as follows:
Step 1: Calculate the exponent expression -3^0. According to the exponent rules, any number raised to the power of 0 is equal to 1. Therefore, -3^0 equals -1.
Step 2: Add the result from step 1 (-1) to 4.5.
The correct answer is -1 + 4.5 = 3.5.
Therefore, the correct answer is:
3^0 + 4.5 = -1 + 4.5 = 3.5
To solve the expression -3^0 + 4.5, we need to follow the correct order of operations, which is typically expressed by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
In this particular expression, there is only one operation to perform: raising -3 to the exponent 0. According to the rules of exponentiation, any number raised to the power of 0 is equal to 1. Therefore, -3^0 simplifies to 1.
Now our expression becomes 1 + 4.5. Adding 1 and 4.5 gives us 5.5.
Therefore, the correct process of solving -3^0 + 4.5 is:
-3^0 + 4.5 = 1 + 4.5 = 5.5
