I recently had this expression:
(4715*7^(3/2)+87472) / (59460*sqrt(7)+157710)
returned as the solution to a set of non-linear equations. Now
by multiplying numerator and denominator by
59460*sqrt(7)-157710
and simplifying with radcan, this expression simplifies to
(\sqrt(7)+14)/30
which is far simpler. But is there any more direct way of simplifying such
an expression? Or, is there any way of obtaining the expression
59460*sqrt(7)-157710
from the original output, without either copying or pasting, or fiddling
about with parts of expressions? I mean, if
b:(4715*7^(3/2)+87472) / (59460*sqrt(7)+157710);
then I could write
c:part(b,2,1)-part(b,2,2);
and then
radcan(radcan(num(b)*c)/radcan(denom(b)*c));
This works fine - but I'm wondering if there's a more direct way.
