Answer 1

I can do that, but a few expressions have their radicands missing or the √ got garbled. I’ll classify the ones that are clear, then list the ambiguous ones and the classifications under the most likely interpretations — tell me if any of those interpretations are wrong.

Clear ones:
- 0.5 + 34 = 34.5 → Rational
- 2π + 7 → Irrational (π is irrational; rational + irrational = irrational)
- 0.5 → Rational
- 3.5 × 4.3 = 15.05 → Rational
- 7π → Irrational

Ambiguous items (please confirm radicands). If we interpret them as shown below, their types are:
- "23×5–√" — likely meant 23 × √5 → 23·√5 is Irrational
- "3–√+25" — likely meant 3 − √25 → 3 − 5 = −2 → Rational
- "2–√" — likely meant 2 − √2 → Irrational
- "49−−√" — likely meant √49 → 7 → Rational

If you confirm or correct the radicands, I’ll mark every expression definitively.
