Question

√5 + 2 is a rational number.

Answer 1

Answer:

No, it is not a rational number, by proof given below.

Step-by-step explanation:

so let's prove it by giving direct proof.

(root 5) + 2 is rational, so it is p/q form.

so (root 5) + 2 =p/q

so, (root 5) = p/q -2 ......we shifted 2 on other side, so it became negative.

But,  the left hand side is an irrational number. (as shown below)

(root 5)=p/q - 2

so we understand that (root 5) + 2 is irrational.
