Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 41 }$ to precision 6.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 41 }$: $ x^{2} + 38 x + 6 $
Roots:
$r_{ 1 }$ $=$ $ 14 a + 28 + \left(5 a + 20\right)\cdot 41 + \left(22 a + 37\right)\cdot 41^{2} + \left(36 a + 27\right)\cdot 41^{3} + \left(2 a + 13\right)\cdot 41^{4} + \left(6 a + 31\right)\cdot 41^{5} +O\left(41^{ 6 }\right)$
$r_{ 2 }$ $=$ $ 13 a + 15 + \left(6 a + 20\right)\cdot 41 + \left(33 a + 19\right)\cdot 41^{2} + \left(20 a + 16\right)\cdot 41^{3} + \left(34 a + 6\right)\cdot 41^{4} + \left(39 a + 23\right)\cdot 41^{5} +O\left(41^{ 6 }\right)$
$r_{ 3 }$ $=$ $ 28 a + 13 + \left(34 a + 26\right)\cdot 41 + \left(7 a + 30\right)\cdot 41^{2} + \left(20 a + 4\right)\cdot 41^{3} + \left(6 a + 7\right)\cdot 41^{4} + \left(a + 26\right)\cdot 41^{5} +O\left(41^{ 6 }\right)$
