Step-by-step explanation:

Let us assume that 7

5

is rational number

Hence 7

5

can be written in the form of

b

a

where a,b(b

=0) are co-prime

⟹7

5

=

b

a

5

=

7b

a

But here

5

is irrational and

7b

a

is rational

as Rational

=Irrational

This is a contradiction

so 7

5

is a irrational number
