1 answer

To determine which expression results in the answer of 1, let's analyze each option:

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

    • \( (7.42)^0 = 1 \) (Any non-zero number raised to the power of 0 is 1)
    • So, \( 13 - 1 = 12 \)

  2. \( 3(8^0) \):

    • \( (8)^0 = 1 \)
    • So, \( 3 \times 1 = 3 \)

  3. \( (-2.97)^0 \):

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

  4. \( 50 + 90 \):

    • \( 50 + 90 = 140 \)

Among these options, the expressions:

  • \( 13 - (7.42)^0 = 12 \)
  • \( 3(8^0) = 3 \)
  • \( (-2.97)^0 = 1 \)
  • \( 50 + 90 = 140 \)

The only expression that evaluates to 1 is \( (-2.97)^0 \).
