1 answer

To determine which of the given options is rational, let's analyze each one:

  1. √3 + √3: This can be simplified to 2√3. Since √3 is irrational, 2√3 is also irrational.

  2. √3 × √3: This simplifies to 3, which is a rational number.

  3. √3 / 1: This is equal to √3, which is irrational.

  4. 1 / √3: This can be rationalized to √3 / 3, which is still irrational.

From the above analysis, the only rational option is √3 × √3 = 3.
