On March 25, 2007 11:54 AM Ondrej Certik asked:

... how can I calculate the limit:

\lim_{x \rightarrow +\infty}(3^x+5^x)^{1/x} 

The result is 5 as you can check by hand:

(3^x+5^x)^{1/x} = 5 <em> ((3/5)^x+1)^{1/x} \rightarrow 5 

When I tried that in axiom:

limit((3^x+5^x)^(1/x), x=%plusInfinity)

Type: Union(OrderedCompletion?(Expression(Integer)),...)

or the equivalent problem:

limit((3^(1/x)+5^(1/x))^(x), x=0, "right")

Type: Union(OrderedCompletion?(Expression(Integer)),...)

I got "failed".

Now it works.
