Answer 1

To determine which number is irrational, let's analyze each option:

1. √9: This equals 3, which is a rational number.
2. √8: This can be simplified to \(2\sqrt{2}\), which is an irrational number (since √2 is irrational).
3. 0.3333...: This represents the repeating decimal \( \frac{1}{3} \), which is a rational number.
4. 2/3: This is a fraction, representing a rational number.

Among these options, the only irrational number is √8.
