3 answers

Here are the correct answers for your questions based on the Zero Power Rule and arithmetic operations:

  1. Which of the following is developed to result in the answer of 1?

    • Answer: (−2.97)⁰
    • Explanation: According to the Zero Power Rule, any non-zero number raised to the power of zero equals 1.
  2. Which of the following shows the correct process of solving −30+4.5?

    • Answer: −30+4.5=−3⁰+4.5=1+4.5=5.5
    • Explanation: This is the only option that correctly shows the Zero Power Rule being applied (since -3 is equivalent to (-3) raised to the power of 1).
  3. Which of the following is an equivalent expression to 7(−5.3)⁰+4·9 when applying the Zero Power Rule?

    • Answer: 71+4·9
    • Explanation: Using the Zero Power Rule, (−5.3)⁰ = 1, so this becomes 7(1) + 4·9.
  4. Which of the following is an equivalent expression to 12(9−70)+(−29)⁰?

    • Answer: 12(9−1)+1
    • Explanation: This is correct because (−29)⁰ = 1, thus simplifying the expression correctly.
  5. Which of the following shows the correct process of solving −4(3+120)+150 using the Zero Power Rule?

    • Answer: −4(3+120)+150=−4(3+1)+1=−4·4+1=−16+1=−15
    • Explanation: This option correctly applies the Zero Power Rule (12⁰ = 1) and maintains the right arithmetic throughout the equation.

number 2 is −3^0+4.5=−1⋅3^0+4.5=−1⋅1+4.5=−1+4.5=3.5

Thank you for your patience. Let’s analyze your assertion for Question 2 again.

To solve \(-30 + 4.5\) using the Zero Power Rule:

  1. Simplify \(-30\) using the expression: \[ -30 = -3 \times 10 \] Here we can interpret \(-3\) in terms of zero power, but notice that the goal is calculating the sum directly with \(4.5\).

  2. Analyzing the old approach:

    • Using the Zero Power Rule: \[ -3^0 + 4.5 = -1 \cdot 3^0 + 4.5 = -1 \cdot 1 + 4.5 = -1 + 4.5 = 3.5 \] This calculation is incorrect because \( -30\) simplifies directly to \( -30 + 4.5\).
  3. The correct process should be:

    • \(-30 + 4.5\)
    • That gives: \[ -30 + 4.5 = -25.5 \]

The statement regarding \(-3^0 + 4.5\) resulting in \(3.5\) is indeed incorrect if you look at it through how \( -30 + 4.5\) should directly go. The issue is using the term \(-3^0\) does not accurately represent \(-30\).

Conclusion for Question 2:

None of the options actually computes to \(-30 + 4.5\). If you appreciate using the Zero power method, that transitional calculation can lead to incorrect understanding.

Hence, the statement for “the correct process” using \(-30\) still relies on straightforward arithmetic.

If you have further comments or corrections about my previous conclusions, please let me know!
