Hi!
I'm a new Axiom user, so this is probably a very simple question, but it
really puzzles me:
(1) -> solve(x^10-1024, 1)
(1) [x= - 2,x= 2]
Type: List Equation Polynomial Fraction Integer
(2) -> solve(2^x-1024, 1)
There are 20 exposed and 3 unexposed library operations named solve
having 2 argument(s) but none was determined to be applicable.
Use HyperDoc Browse, or issue
)display op solve
to learn more about the available operations. Perhaps
package-calling the operation or using coercions on the arguments
will allow you to apply the operation.
Cannot find a definition or applicable library operation named solve
with argument type(s)
Expression Integer
PositiveInteger
Perhaps you should use "@" to indicate the required return type,
or "$" to specify which version of the function you need.
(2) ->
First question: What is so different about those two expressions?
Second question: How do I fix it?
The problem I actually wanted to solve was:
solve((250/x)^x-6000000000,1.e-5)
..which also doesn't work, but I expect that the answer to that will be
clear to me when my second question from above is answered.

Cheers, SÃ¸ren.
