Defining polynomial
$f(x)$ | $=$ | \( x^{5} - x^{4} - 5x^{3} + 3x^{2} + 5x - 2 \) . |
The roots of $f$ are computed in an extension of $\Q_{ 47 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 47 }$: \( x^{2} + 45x + 5 \)
Roots:
$r_{ 1 }$ | $=$ | \( 21 + 25\cdot 47 + 5\cdot 47^{2} + 25\cdot 47^{3} + 6\cdot 47^{4} +O(47^{5})\) |
$r_{ 2 }$ | $=$ | \( 2 a + 16 + \left(35 a + 1\right)\cdot 47 + \left(39 a + 28\right)\cdot 47^{2} + \left(35 a + 22\right)\cdot 47^{3} + \left(8 a + 2\right)\cdot 47^{4} +O(47^{5})\) |
$r_{ 3 }$ | $=$ | \( 22 + 5\cdot 47 + 33\cdot 47^{2} + 9\cdot 47^{3} + 29\cdot 47^{4} +O(47^{5})\) |
$r_{ 4 }$ | $=$ | \( 16 + 39\cdot 47 + 47^{2} + 29\cdot 47^{3} + 24\cdot 47^{4} +O(47^{5})\) |
$r_{ 5 }$ | $=$ | \( 45 a + 20 + \left(11 a + 22\right)\cdot 47 + \left(7 a + 25\right)\cdot 47^{2} + \left(11 a + 7\right)\cdot 47^{3} + \left(38 a + 31\right)\cdot 47^{4} +O(47^{5})\) |
