Question

Prove that 1/√2 is irrational

Answer 1

Explanation:

• Let's assume that it is rational , so this number can be represented as

`\Large \boldsymbol{}\bf (p^(^/is \ an \ integer))/(q^( / natural)) -irreducible \ \ fraction`

`\Large \boldsymbol{}\bf (1 ^(/ an \ integer ))/(√(2)^( / not \ \ integer ) )` -Since the denominator is not a natural number then the 1/√2 is respectively an irrational number
