Question

prove that 2+3/5√13 is not rational​

Answer 1

Answer:

Let,2+3/5√13=P (where pis rational no.)

          3/5√13=P-2

                √13=P-2*5/3

But it is not possible because LHS is irrational and RHS is rational no.

this contradict the fact that 2+3/5√13 is rational no.

therefore,Our assumption is wrong that 2+3/5√13 is rational no.

Hence, 2+3/5√13 is not rational no.
