Well I needed two surds one of which was 5 times the other, so anything
like 5 sqrt(n) and sqrt(n) will do, Now 5 sqrt(n) = sqrt(25 n), so now we
choose any n and sqrt(25 n)/sqrt(n) will do the trick, as long as n is not a
perfect square when the numerator and denominator will be integers -
which we do not want.

No it has to be rational when all reduced to lowest form, as it has to
be 5, which is an integer but may be written 5/1 so is rational.
What you want is for both the numerator and denominator to be irrational,
as sqrt(125) and sqrt(5) are.
(there is no irrational number equal to 5)
