Question

# Show that 5/5 is an irrational number.

Solution If possible, let 5V3 be a rational number.
So, 53 = p q where p and q are co-prime integers and
q=0
So, ſ3= 2
So, R.H.S is a rational number and hence 13 is also rational
which is a contradiction.
So our supposition is wrong. Hence, 5 is an irrational number
