Answer 2

Answer:

irrational

Step-by-step explanation:

Definition of Irrational numbers-

A number which when written in p/q form is the estimation of that number. Eg- 1/3≈0.333....... and 22/7≈3.142....

20*5-5=19*5   (a property)

Let us relate this property

20$\sqrt{5}$-

Since, $\sqrt{5}$ cannot be simplified more,

a*infinite=infinite

let us us take a as 19 as b (or infinite) as $\sqrt{5}$ because

19*$\sqrt{5}$=irrational as 19*irrational=irrational.
