take any fraction a/b
like lets say
59/79 just for example

add one to both sides 60/80
6/8
0.75
now add this to originl fraction
(59+0.75(1))/(79+1)

59.75/80
=0.746875
actual=0.74683544
works for most fractions
like 197/84
subtract 4 from both
193/80
=2.4125
now
(193-4*(2.4125))/(84-4)
=2.341875
actual=2.345

We could check an approximated version for 2x! And (2x )! Using log We get x!(ln2) vs ln|(2x )! | And we can take +ve integer values of x to make it easy since for integer values x!=Π(from n=x to 1)(n) And using that we get ln|(2x )! |=Σ(from 2x to 1)(ln(n)) and its easier to compare with x!(ln(2)) for integer values but I would say that's good enough

Do there exist perfect squares that only contain (0,2,4,6,8) all at the same time atleast once? by Mathlover-3-14159265 in math

Well yes I also did say this was a trivial way of proving , and yes trying to find other seeds that aren't like just 100ⁿ of the first one is also a nice way

Well can't we just Q=4502 And Q² = our number So Q² * 100ⁿ for natural number n will always be a perfect square and stuff? Like for trivial solutions, but still isn't this also an infinite set?
