Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 73 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 73 }$: $ x^{2} + 70 x + 5 $
Roots:
$r_{ 1 }$ $=$ $ 30 a + 35 + \left(70 a + 43\right)\cdot 73 + \left(48 a + 46\right)\cdot 73^{2} + \left(12 a + 62\right)\cdot 73^{3} + \left(47 a + 59\right)\cdot 73^{4} +O\left(73^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 4 a + 60 + \left(35 a + 31\right)\cdot 73 + \left(46 a + 45\right)\cdot 73^{2} + \left(48 a + 44\right)\cdot 73^{3} + \left(18 a + 50\right)\cdot 73^{4} +O\left(73^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 29 + 43\cdot 73 + 66\cdot 73^{3} + 2\cdot 73^{4} +O\left(73^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 43 a + 52 + \left(2 a + 5\right)\cdot 73 + \left(24 a + 50\right)\cdot 73^{2} + \left(60 a + 51\right)\cdot 73^{3} + \left(25 a + 42\right)\cdot 73^{4} +O\left(73^{ 5 }\right)$
$r_{ 5 }$ $=$ $ 23 a + 61 + \left(19 a + 72\right)\cdot 73 + \left(43 a + 53\right)\cdot 73^{2} + \left(36 a + 37\right)\cdot 73^{3} + \left(69 a + 62\right)\cdot 73^{4} +O\left(73^{ 5 }\right)$
$r_{ 6 }$ $=$ $ 69 a + 72 + \left(37 a + 59\right)\cdot 73 + \left(26 a + 3\right)\cdot 73^{2} + \left(24 a + 71\right)\cdot 73^{3} + \left(54 a + 57\right)\cdot 73^{4} +O\left(73^{ 5 }\right)$
$r_{ 7 }$ $=$ $ 50 a + 57 + \left(53 a + 34\right)\cdot 73 + \left(29 a + 18\right)\cdot 73^{2} + \left(36 a + 31\right)\cdot 73^{3} + \left(3 a + 15\right)\cdot 73^{4} +O\left(73^{ 5 }\right)$
