To determine which of the given options equals 1, we need to evaluate each expression.
A. \( 5^0 + 9^0 \)
Since any non-zero number raised to the power of 0 is 1,
\( 5^0 = 1 \) and \( 9^0 = 1 \), so
\( 5^0 + 9^0 = 1 + 1 = 2 \).
B. \( 13 - (7.42)^0 \)
Since \( (7.42)^0 = 1 \), we have
\( 13 - 1 = 12 \).
C. \( (-2.97)^0 \)
Since \( (-2.97)^0 = 1 \), this equals 1.
D. \( 3 (8^0) \)
Since \( 8^0 = 1 \), we have
\( 3 (8^0) = 3 \times 1 = 3 \).
Now we can summarize:
- A: 2
- B: 12
- C: 1
- D: 3
The only option that results in 1 is C. \( (-2.97)^0 \).
