Answer:

[tex] \sqrt{20} \\ - \sqrt{8} \\ - \pi \: t[/tex]

Step-by-step explanation:

irrational numbers are square roots of non squared nubers ( so no sqrt 49 because that is 7), and some numbers found in nature like \pi\ and e.

sqrt 20 = sqrt 5 × sqrt 4 = sqrt 5 × 2

sqrt 8 = sqrt 4 × sqrt 2 = 2 × sqrt 2

sqrt 5 and sqrt 2 are irrational and pi is irational by its own nature.
