Hello !
Very simple :
p = x /. FindRoot[x + Log[x] == 5, {x, 1}]
Greetings !

Objet : [mg38812] Getting rid of the arrow in FindRoot output (newbie
question)
Hi, this is a newbie question, I am just starting to learn how to use
Mathematica.
How do I get rid of the arrow ("->") from the output when using
FindRoot?
E.g.
p := FindRoot[x + Log[x] == 5, {x, 1}]
Print[p]
gives the output
{x -> 3.69344}
and then if I change
Print[p]
to
Print[p + 1]
then the output is
{1 + (x -> 3.69344)}
I need to have the output as a number so as to be able to put it into
other functions and plot it.
Cheers,
David
