Answer:

rational: √81, √121

irrational: √89, √131

Explanation:

You know your squares, so you know that 81 = 9² is a perfect square. Its square root is 9, a rational number.

And you know that 121 = 11², another perfect square. Its square root is 11, a rational number.

The remaining numbers are not the roots of squares of integers, so will be irrational.
