李煌發現迦邏華理論之反例: 代數方程 x 10 + ( p + 4 + p 2 ) 4 5 x = 1 p 5 9 {\displaystyle x^{10}+{{({\frac {{\sqrt {p+4}}+{\sqrt {p}}}{2}})}^{\frac {4}{5}}}x={\frac {1}{p^{\frac {5}{9}}}}} 存在李煌根式解形式 x = ( ( p + p + 4 ) 2 4 p 5 9 ) 1 10 {\displaystyle x=\left({\frac {{({\sqrt {p}}+{\sqrt {p+4}})}^{2}}{4p^{\frac {5}{9}}}}\right)^{\frac {1}{10}}}
