## Question:how to obtain antiderivative without RootOf ?

Maple 2022

I tried different things but can't figure how to make Maple give a simplified result from int command without these RootOf with sums in them. Here is an example.

```restart;
anti:=int(1/(a+x^(1/5)),x);
```

The strange thing is that doing

`eval(anti,a=1)`

Keeps these rootsOf and Sums there. But doing

`anti:=int(1/(1+x^(1/5)),x);`

Gives simplified result without RootOf

I tried DEtools:-remove_RootOf and assumptions and value() but nothing worked. I tried assumptions on a, such as assuming a::integer,a>0 and other things.

I need similar result as Mathematica:

```ClearAll[x, a];
Integrate[1/(a + x^(1/5)), x]```

I am sure there is an option in Maple to do that, i.e. give result without these RootOf and Sums. But so far, I could not find it. I looked at options to int() command also.

Any one know what option to use or how to simplifies it the the above result by Mathematica?
