Answer 2

Step-by-step explanation:

let assume that 3-✓2 is rational,

3-✓2=p/q(where q does not belong to zero)

by moving ✓2 to one side

3-p/q=✓2

here, root 2 is irrational and 3-p/q is rational WHICH CANNOT BE WRITTEN EQUALLY:

so our assumption is wrong ...

this gives that 3-✓2 is irrational..
