Let's analyze each number set and provide the correct descriptions for them:
a) \( (\sqrt{25}, \sqrt{9}, \sqrt{64}) \)
Description: This set consists of the square roots of perfect squares. The numbers are calculated as follows:
\(\sqrt{25} = 5\),
\(\sqrt{9} = 3\),
\(\sqrt{64} = 8\).
So, the set simplifies to \( (5, 3, 8) \).
b) \( (-2.4, 0, 3.1, \sqrt{81}) \)
Description: This set contains both negative, zero, positive real numbers, and a square root. The square root of 81 is 9, so the full set is \( (-2.4, 0, 3.1, 9) \).
c) \( (-gKe, s) \)
Description: This appears to be a set that includes variables or symbolic representations, not specific numbers. It suggests a context where these letters represent certain values but needs further clarity for a specific description.
d) \( (\sqrt{12}, \sqrt{11}, -) \)
Description: This set contains square roots of non-perfect squares and an additional symbol (which could represent some operation, an empty set, or a placeholder). Thus, it's a mix of irrational numbers (since both \(\sqrt{12}\) and \(\sqrt{11}\) are not whole numbers) along with an undetermined symbol. The numerical approximations are approximately \( (3.46, 3.32, -) \).
In summary:
- a) Set of square roots of perfect squares.
- b) Set of real numbers (includes negative, zero, positive, and a square root).
- c) Set of symbolic variables.
- d) Set of square roots of irrational numbers and an unspecified symbol.
