You can use the `radical_expression`

method:

```
sage: a = AA(sqrt(3)+sqrt(2))
sage: a
3.146264369941973?
sage: a.radical_expression()
sqrt(2*sqrt(6) + 5)
```

Note that this is not a "complete" feature, as there might be some algebraic numbers admitting a radical decomposition that this feature will not find.
