To determine which of the inequalities are true, let's evaluate each one step by step.

  1. \( 6 - \sqrt{2} < 2 \)

    • First, calculate \( \sqrt{2} \) which is approximately \( 1.414 \).
    • Therefore, \( 6 - \sqrt{2} \approx 6 - 1.414 = 4.586 \).
    • \( 4.586 < 2 \) is false.
  2. \( 0 < 4 - \sqrt{4} \)

    • Calculate \( \sqrt{4} = 2 \).
    • Therefore, \( 4 - \sqrt{4} = 4 - 2 = 2 \).
    • \( 0 < 2 \) is true.
  3. \( \sqrt{8} < 5 \)

    • Calculate \( \sqrt{8} \) which is approximately \( 2.828 \).
    • \( 2.828 < 5 \) is true.
  4. \( \sqrt{8} > 3 \)

    • We already found \( \sqrt{8} \approx 2.828 \).
    • \( 2.828 > 3 \) is false.
  5. \( \sqrt{8} > \sqrt{6} \)

    • Calculate \( \sqrt{6} \) which is approximately \( 2.449 \).
    • Since \( 2.828 > 2.449 \), this is true.

Based on the evaluations above, the three correct true inequalities are:

  1. \( 0 < 4 - \sqrt{4} \)
  2. \( \sqrt{8} < 5 \)
  3. \( \sqrt{8} > \sqrt{6} \)

Therefore, the true inequalities are the second, third, and fifth responses.
