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:
-
3(80): This expression is equal to 240 and does not equal 1.
-
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.
-
50 + 9⁰: In this expression, 9⁰ equals 1, so it simplifies to 50 + 1 = 51. This does not equal 1.
-
(−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.
