25x16x25x84=25x4x(25x4)x84=100x100x84=840000
78+22x7=78+(20+2)x7=78+20x7+2x7=78+140+14=232
39x102=39x(100+2)=39x100+39x2=3900+78=3978
104x25=(100+4)x25=100x25+4x25=2500+100=2600
{25x13}x4==25x13x4=25x4X13=100X13=1300

在lingo中x1+x2+x3=2,x7+x8>=1用#ge#和#and#怎么编程?具体的线性关系为:max Z=25*x1+ 36*x2+60*x3+ 53*x4+55*x5+17*x6+16*x7+22*x8约束条件为:150*x1+180*x2+300*x3+200*x4+300*x5+100*x6+80*x7+120*x8=1;这是0-1规划我编了一部分,
(11-11/25x7) +(9-11/25x5)+ (7-11/25x3)=?kuai
简便计算 56X1.25 = = = 1.6X7.5X1.25
3/2x(2.25+25/6)x7.7%]-15/13=?
3/2x(2.25+25/6)x7.7%]-15/13=?
1.6x7.5x1.25 过程 简算
1.6x7.5x1.25那么算
(4.5-x)X7=17.
解方程x+2 x7=28
8x-6x7=18
a+b=?,a的平方x7?
线性问题在lingo中的表示minZ=5*x1+7*x2+5*x3+4*x4+6*x5+5*x6+5*x7+3*x8 限制条件25*x1+36*x2+32*x3+15*x4+31*x5+28*x6+22*x7+12*x8>=105.69;然后x1到x8必须是1或者0.这个怎么在lingo软件中正确表示出来
(10+x)x7/2-(10-x)x7/2=28如何解方程
15.37x7.88-9.37x7.88+15.37x2.12-9.37x2.12=
