Which of the following is developed to result in the answer of 1?(1 point) Responses 50+90 5 superscript 0 baseline plus 9 superscript 0 baseline 3(80) 3 left parenthesis 8 superscript 0 baseline right parenthesis (−2.97)0 left parenthesis negative 2.97 right parenthesis superscript 0 baseline 13−(7.42)0

Answer 1

To find which of the provided expressions results in an answer of 1, let's evaluate each option:

1. 50 + 90: This equals 140, which is not 1.

2. 5^0 + 9^0: Any non-zero number raised to the power of 0 equals 1. Thus, \(5^0 = 1\) and \(9^0 = 1\). Therefore, \(5^0 + 9^0 = 1 + 1 = 2\), which is not 1.

3. 3(80): This equals 240, which is not 1.

4. 3(8^0): Since \(8^0 = 1\), this becomes \(3 \times 1 = 3\), which is not 1.

5. (−2.97)^0: Any non-zero number raised to the power of 0 equals 1. Thus, \((-2.97)^0 = 1\), which is 1.

6. 13 − (7.42)^0: Here, \( (7.42)^0 = 1\), so the expression becomes \(13 - 1 = 12\), which is not 1.

After reviewing all options, the expression that results in the answer of 1 is:

(−2.97)^0.
