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

Question

options:

13 − (7.42)^0

(−2.97)^0

5^0+9^0
5 superscript 0 baseline plus 9 superscript 0 baseline

3(8^0)

Answer 1

To determine which of the given expressions results in an answer of 1, we can evaluate each option:

1. \( 13 - (7.42)^0 \):

   • \((7.42)^0 = 1\)
   • Thus, \( 13 - 1 = 12\) (not equal to 1).

2. \((-2.97)^0\):

   • \((-2.97)^0 = 1\) (since any non-zero number raised to the power of 0 is 1).

3. \(5^0 + 9^0\):

   • \(5^0 = 1\) and \(9^0 = 1\)
   • Thus, \(1 + 1 = 2\) (not equal to 1).

4. \(3(8^0)\):

   • \(8^0 = 1\)
   • Thus, \(3 \times 1 = 3\) (not equal to 1).

From the evaluations, the expression that results in 1 is:

((-2.97)^0.
