$\frac{ \sqrt{5} }{1} \\ \sqrt{5} =irrational \: number \\ 1 = rational number \\ (l.h.s = not \: r.h.s) \\ therefore \: \sqrt{5} is \: a \: irrational \: number.... \\ hope \: its \: helps.......$

Answer 2

Answer:

Let √5 is a rational no.

we can write it in the form of p/q

√5 = p/q

sq.on both sides

5 = p^2/q^2

5 q^2 = p^2--1)

5 divides p

let p= 5x

put in eq.1

25x^2 = 5q^2

5 also divides q

but it is our assumption

so √5 is an irrational no.
