multipliying by 1000000 on both sides
subtracting eq 1 by eq 2
x=27142857  /  999999
hence the prime factorisation of the denominator contains factor more than 2 or 5

Actually we need to prove that 2√3-1 is a irrational no..
so for that let us take that 23 -1is a rational  num as a contradiction.
so let 2
3-1 be equal to a/b(where a,b are co primes)
we took it becoz a rational num ill be in the form a/b
here a+b/2b is a ratinal num but 3 is a irrational num.
so our assumption that 2
3-1 is rational num is a contradiction.

so,from this we can say that 2
3-1 is a irrational num.
