3(80)

Answer 1

To find which expression results in the answer of 1, we can evaluate each option:

1. **(−2.97)⁰**: Any non-zero number raised to the power of 0 is 1. Therefore, \((−2.97)⁰ = 1\).

2. **13 − (7.42)⁰**: Here, \((7.42)⁰ = 1\), so \(13 - 1 = 12\).

3. **5⁰ + 9⁰**: Both \(5⁰ = 1\) and \(9⁰ = 1\). Thus, \(1 + 1 = 2\).

4. **3(80)**: This expression evaluates to \(3 \times 80 = 240\).

From the evaluation, we see that the expression that results in 1 is **(−2.97)⁰**.
