Answer 1

To find the expression that results in the answer of 1, we need to recall that any non-zero number raised to the power of 0 is equal to 1.

Let's analyze each response:

1. **3(80)**: This expression is equal to 240 and does not equal 1.

2. **13 − (7.42)⁰**: Here, (7.42)⁰ is equal to 1, so the expression simplifies to 13 - 1 = 12. This does not equal 1.

3. **50 + 9⁰**: In this expression, 9⁰ equals 1, so it simplifies to 50 + 1 = 51. This does not equal 1.

4. **(−2.97)⁰**: This expression is equal to 1 since any non-zero number raised to the power of 0 is 1.

The correct answer is **(−2.97)⁰**.
