请假一下可否用lingo如何求解下面的非线性0-1规划的解?目标函数是:f=300000/(4364.64*(x(1)+x(2)+x(3)+x(4)+x(5)+x(6))+10392*(x(7)+x(8)+x(9)+x(10)+x(11)+x(12)+x(13)+x(14)+x(15)+x(16)+x(17)+x(18)+x(19)+x(20)+x(21)+x(22)+x(23)+x(24
已知x=13/(4+根号3),求(x^4-6x^3-2x^2+18x+23)/(x^2-8x+15) 的值 禁止复制粘贴:x=13/(4+√3)=4-√3√3=4-x3=x²-8x+16x^2-8x+13=0,所以x^2-8x+15=2;x^4-6x^3-2x^2+18x+23=x^2(x^2-8x+13)+2x^3-15x^2+18x+23=2x(x^2-8x+13)+x^2-8x+23=x^2-8x+2
