# why won't simplify square roots?

sage: assume(x>2)

sage: sqrt(x^2 - 2*x + 1).simplify_full()

sqrt(x^2 - 2*x + 1)

why won't simplify square roots?

sage: assume(x>2)

sage: sqrt(x^2 - 2*x + 1).simplify_full()

sqrt(x^2 - 2*x + 1)

You can use the `canonicalize_radical`

method for that:

```
sage: e = sqrt(x^2 - 2*x + 1)
sage: e.canonicalize_radical()
x - 1
```

However, the assumptions are not taken into account, please read the warning in the doc:

```
sage: e.canonicalize_radical?
```

.canonicalize_radical() produces incorrect result

simplify_full() and symbolic vectors

equation not simplifying and substituting properly

simply_full for expressions with exponents

(abs(sin(x))^2).simplify_full()

simplification errors in simple expressions
