{x} + {y} is either 0 or 1

Now can you try?

1

sir how {x} + {y} =0 /1

sir am doing it in this way.....

let x= I₁+ f₁ nd y=I₂+ f₂

so we can write ...

[ I₁+ f₁].[I₂+ f₂]= f₁ +I₂+ f₂ + I₁

i.e ... I₁ . I₂ = I₁ + I₂ + f₁ + f₂

sir, how to proceed from here..............?

62

that is fairly correct..

now observe that LHS is an integer..

so RHS has to be an integer.. so RHS has to be either 0 or 1..

now can you proceed?
