Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 29 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 29 }$: $ x^{2} + 24 x + 2 $
Roots:
$r_{ 1 }$ $=$ $ 2 + 27\cdot 29 + 28\cdot 29^{2} + 16\cdot 29^{3} + 24\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 10 a + 22 + \left(4 a + 19\right)\cdot 29 + \left(12 a + 5\right)\cdot 29^{2} + \left(10 a + 26\right)\cdot 29^{3} + \left(17 a + 10\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 6 a + 11 + \left(21 a + 6\right)\cdot 29 + \left(20 a + 15\right)\cdot 29^{2} + \left(23 a + 4\right)\cdot 29^{3} + \left(24 a + 27\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 26 a + 21 + \left(17 a + 17\right)\cdot 29 + 18\cdot 29^{2} + \left(19 a + 18\right)\cdot 29^{3} + \left(25 a + 9\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 23 a + 12 + \left(7 a + 19\right)\cdot 29 + \left(8 a + 10\right)\cdot 29^{2} + \left(5 a + 15\right)\cdot 29^{3} + \left(4 a + 11\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 19 a + 14 + \left(24 a + 2\right)\cdot 29 + \left(16 a + 4\right)\cdot 29^{2} + \left(18 a + 8\right)\cdot 29^{3} + 11 a\cdot 29^{4} +O\left(29^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 3 a + 6 + \left(11 a + 23\right)\cdot 29 + \left(28 a + 3\right)\cdot 29^{2} + \left(9 a + 26\right)\cdot 29^{3} + \left(3 a + 2\right)\cdot 29^{4} +O\left(29^{ 5 }\right)$
