Expert Solution

Step 1

according to given data

$\begin{array}{rcl} n a t u r a l n u m b e r s & = & \{\sqrt{81}\} \\ w h o l e n u m b e r s & = & \{0, \sqrt{81}\} \\ i n t e g e r s & = & \{- 17, 0, \sqrt{81}\} \\ r a t i o n a l n u m b e r s & = & \{- 17, - \frac{9}{13}, 0.75, \sqrt{81}\} \\ i r r a t i o n a l n u m b e r s & = & \{\sqrt{2}, π\} \\ r e a l n u m b e r s & = & \{- 17, - \frac{9}{13}, 0, 0.75, \sqrt{2}, π, \sqrt{81}\} \end{array}$
