I have several expressions in a series, such as

```
1/4 (-(1/4) + Sqrt[5]/4 + I Sqrt[5/8 + Sqrt[5]/8]) (-1 - Sqrt[5] + 2 Sqrt[7/2 + (5 Sqrt[5])/2])

```

If I run `FullSimplify` over it, it returns a `Root` object,

```
Root[1 + #1 + 3 #1^2 + 5 #1^3 + 6 #1^4 + 5 #1^5 + 7 #1^6 + 2 #1^7 + #1^8 &, 8]

```

which is rather useless for further computation. Of course, using `ToRadicals` (which seems to be the general answer I've found for this situation) does not work with a degree 8 polynomial. The full expressions are very cumbersome, and using only `Simplify` is not enough. So I need to run `FullSimplify` over them.

The only solutions I've found so far, as I said, rely either on `ToRadicals`, or in not using `FullSimplify` at all.

Does anybody know how to stop `FullSimplify` from returning these objects, while still being able to do the simplifications?

Thanks!
