CAS SOLVE uses numeric strategy
Answered
Dear developers,
using :
SOLVE[x⁵ + x = 2.34]
on Geogebra 5.0.119.03D results to
{x = 1.051932190632}.
But this is a numeric solution, not an algebraic!
This is NOT according to the documentation  and might confuse students at school..
I would prefer:
 Either: No result, or
 not an = sign, instead an 'appoximate' sign.
What do you think?
Thank you
Thomas

Hi,
You posted an inexact (approximate) expression 2.34.
So the answer you get is the appropriate one.
If you want exact solution try the same problem with 234/100.
Sorry, I misread the degree.
In that case there is NO easy solution. You either obtain the one you already received OR
as is the case in many CAS's
a more confusing one as RootOf[x^5 + x  2.34, X], where X is a number assigned by the system.
Pick and choose.
... thanks for the reply.
A third solution would be writing
{x≈1.051932190632}
instead of
{x=1.051932190632}
if a numeric solution is presented.
What do you think?
Thx
Thomas
I see what you mean. I personally do not think it is necessary.
The dot after 1 tells the whole story.
Sorry, we won't be changing this. The current solution is a good, pragmatic compromise
