Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 7 }$ to precision 10.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 7 }$: $ x^{2} + 6 x + 3 $
Roots:
$r_{ 1 }$ $=$ $ 1 + 3\cdot 7 + 7^{2} + 4\cdot 7^{3} + 2\cdot 7^{4} + 3\cdot 7^{6} + 7^{7} + 7^{8} + 2\cdot 7^{9} +O\left(7^{ 10 }\right)$
$r_{ 2 }$ $=$ $ 3 a + 5 + \left(3 a + 1\right)\cdot 7 + a\cdot 7^{2} + 2\cdot 7^{3} + 2\cdot 7^{4} + 6 a\cdot 7^{5} + 2 a\cdot 7^{6} + \left(6 a + 1\right)\cdot 7^{7} + \left(a + 5\right)\cdot 7^{8} + \left(2 a + 5\right)\cdot 7^{9} +O\left(7^{ 10 }\right)$
