解 1
a = -sqrt(3^(1/6)*(9*%i+13*sqrt(3))^(1/3)+sqrt(3)*14^(2/3)/(9*%i+13*sqrt(3))^(1/3)+2*3^(1/3)*14^(1/3))/(3^(2/3)*14^(1/6))
解 2
a = sqrt(3^(1/6)*(9*%i+13*sqrt(3))^(1/3)+sqrt(3)*14^(2/3)/(9*%i+13*sqrt(3))^(1/3)+2*3^(1/3)*14^(1/3))/(3^(2/3)*14^(1/6))
解 3
a = -sqrt(3^(2/3)*%i*(9*%i+13*sqrt(3))^(1/3)-3^(1/6)*(9*%i+13*sqrt(3))^(1/3)-3*14^(2/3)*%i/(9*%i+13*sqrt(3))^(1/3)-sqrt(3)*14^(2/3)/(9*%i+13*sqrt(3))^(1/3)+4*3^(1/3)*14^(1/3))/(sqrt(2)*3^(2/3)*14^(1/6))
解 4
a = sqrt(3^(2/3)*%i*(9*%i+13*sqrt(3))^(1/3)-3^(1/6)*(9*%i+13*sqrt(3))^(1/3)-3*14^(2/3)*%i/(9*%i+13*sqrt(3))^(1/3)-sqrt(3)*14^(2/3)/(9*%i+13*sqrt(3))^(1/3)+4*3^(1/3)*14^(1/3))/(sqrt(2)*3^(2/3)*14^(1/6))
解 5
a = -sqrt(-3^(2/3)*%i*(9*%i+13*sqrt(3))^(1/3)-3^(1/6)*(9*%i+13*sqrt(3))^(1/3)+3*14^(2/3)*%i/(9*%i+13*sqrt(3))^(1/3)-sqrt(3)*14^(2/3)/(9*%i+13*sqrt(3))^(1/3)+4*3^(1/3)*14^(1/3))/(sqrt(2)*3^(2/3)*14^(1/6))
解 6
a = sqrt(-3^(2/3)*%i*(9*%i+13*sqrt(3))^(1/3)-3^(1/6)*(9*%i+13*sqrt(3))^(1/3)+3*14^(2/3)*%i/(9*%i+13*sqrt(3))^(1/3)-sqrt(3)*14^(2/3)/(9*%i+13*sqrt(3))^(1/3)+4*3^(1/3)*14^(1/3))/(sqrt(2)*3^(2/3)*14^(1/6))
