Defining polynomial
$f(x)$ | $=$ | \( x^{4} - 190x^{2} + 7220 \) . |
The roots of $f$ are computed in $\Q_{ 79 }$ to precision 5.
Roots:
$r_{ 1 }$ | $=$ | \( 1 + 66\cdot 79 + 44\cdot 79^{2} + 41\cdot 79^{3} + 39\cdot 79^{4} +O(79^{5})\) |
$r_{ 2 }$ | $=$ | \( 30 + 49\cdot 79 + 38\cdot 79^{2} + 9\cdot 79^{3} + 17\cdot 79^{4} +O(79^{5})\) |
$r_{ 3 }$ | $=$ | \( 49 + 29\cdot 79 + 40\cdot 79^{2} + 69\cdot 79^{3} + 61\cdot 79^{4} +O(79^{5})\) |
$r_{ 4 }$ | $=$ | \( 78 + 12\cdot 79 + 34\cdot 79^{2} + 37\cdot 79^{3} + 39\cdot 79^{4} +O(79^{5})\) |
