Unexpected Indeterminate result from evaluating a limit [closed]

Question

Consider

$\qquad \underset{h\to 0}{\text{lim}}\dfrac{\sqrt[4]{h+x}-\sqrt[4]{x}}{\sqrt{h+x}-\sqrt{x}}$

Here is what I get when I evaluate it Mathematica:

When I calculate it by hand and in other applications, it results in

$\qquad \dfrac{1}{ 2 \sqrt[4]{x}}$

Syntax error in Mathematica?

Update

It is not that I do not know how to calculate the limit, I have easily done it by hand without derivatives and with the rule of L'hopital. I find it strange, that when writing it using one of the assistant palettes, it evaluated to Indeterminate. I imagined that I had to put an extra condition.

That's why I thought maybe I needed a condition for x , let's say x > 0, but I didn't know how to write it.

This result threw me. Now, I did it again and it I got the correct result (maybe some variable in memory was bothering me).

Answer 1

Responding to the only question-like feature of the edited Question,

Assuming[{x > 0},
    Limit[ /* more stuff here */ ]
]

Answer 2

Mathematica

Limit[((h + x)^(1/4) - ( x)^(1/4))/((h + x)^(1/2) - ( x)^(1/2)),h -> 0]
(*1/(2 x^(1/4))*)

evaluates the limit without problems
