Question 1066670
{{{13^2=169}}}, starting from rational, ending in the computed value.
{{{sqrt(169)=13}}}



{{{sqrt(0.4049586776859)}}}, but so that is not finished being expressed...;

{{{sqrt(0.4049586776859)=sqrt((7/11)^2)=7/11}}}
and {{{7/11}}} is too, a rational number.



These are just examples.  You can find many, many more.
