Step-by-step explanation:
Let us consider that √5 is a “rational number”.
We were told that the rational numbers will be in the “form” of \frac {p}{q}qp form Where “p, q” are integers.
So, \sqrt { 5 } = \frac {p}{q}5=qp
p = \sqrt { 5 } \times qp=5×q
we know that 'p' is a “rational number”. So 5 \times q should be normal as it is equal to p
But it did not happens with √5 because it is “not an integer”
Therefore, p ≠ √5q
This denies that √5 is an “irrational number”
So, our consideration is false and √5 is an “irrational number”."
