단순화된 값 : -xy ( x2y-yxyyxyxyxyxyxyxyxyxyyy ) , xy-2입니다 .

원래 공식은 =x3y6+x2y+x2y2+xy2xy2xy2xy2xy2xy2xy2xy2xy+4-242입니다 .

식을 간단히 하기 위해서 : 주어진 x+yy+y.75 , xy+xy+y2xy의 3승을 구하시오

x^3+xy^2y^2y^2x^2y =xx^2+y^2xxy^2xxxxxxxxxxxxy2xxxxxxxxy2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxy2xxxxxxxxxxy = 2xxxxyxyxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxy = 2xxxxxxxxxxxxxxxy2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxy2xxxxxxxxxxxxxxxxxxxxxy + 2xxxxxxxxxxxxxxxxxxxxxxxxxxxy + 2xy = 2x
