# Automatic expression.maxima_methods().rootscontract() ?

I have to compare quite a lot expressions and I like to do it with Sage. Sadly something like

```
sqrt(x^3)/sqrt(x^2) == sqrt(x)
```

gives false in default mode sage. Here

```
expression.maxima_methods().rootscontract()
```

does help, but is there a automatic way doing that, at least for one notebook? (Btw, why is it not the default?) Shouldn't at least simplify_full be enough to trigger that?

Maybe worth another question: Are there other pitfalls like this, I should be aware of?
