Answer 1

Hi there !

To prove :-

4-3√2 / 5 is irrational

Proof :-
Lets assume that 4-3√2 / 5 is rational

Let ,
4-3√2 / 5 = r , where r is rational.

4 -  3√2  = 5r

-  3√2  = 5r -4

√2  = 5r -4 /-3

Here ,
its very clear that RHS is rational
On the other hand , LHS is irrational.
This is a contradiction.
Hence , our assumption was wrong.

Therefore , 4-3√2 / 5 is irrational

Answer 2

u can prove 3√2 irrational and then rite a statement that basic operations between rational and irrational result in irrational
