A irrasional number between 5 And 7

Let's use pi

irrational times rational=irrational

pi≈3.14

so double that is

2pi≈6.28

that's beteween 5 an d7

so an irrational number between 5 and 7 is 2pi

we could also do

remember that square roots of non-perfece square numbers are usually irraitonal

5²=25

7²=49

so an irrational number could be √c where 25
example, √40

some irrational numbers are 2π nd √40
