To determine which of the given expressions is rational, let's simplify each option:
1. **√3 + √3**: This simplifies to \(2\sqrt{3}\), which is not a rational number since \(\sqrt{3}\) is irrational.
2. **√3 × √3**: This simplifies to \(\sqrt{3} \times \sqrt{3} = 3\). This is a rational number since it is an integer.
3. **√3/1**: This is simply \(\sqrt{3}\), which is not a rational number.
4. **13√**: This option seems ambiguous but assuming it means \(13\sqrt{3}\). This is also not a rational number since it has \(\sqrt{3}\) in it.
From the above options, only the second expression, **√3 × √3** (which equals 3), is a rational number.
Thus, the answer is:
**√3 × √3**
