xy乘yx等于3154,x,y等于几是一道乘法数式题．
x=3或8 y=8或3总之,就是38和83

x=3,y=8~先开根号~得到56~然后看~最后是4,~带4的~又要小于56的,那只有是3*8

38*83

3和8

这是一道不定方程
x^2*y^2=3154
x^2=3154/y^2
解之得：
x=1 y=56.1604843283959x=2 y=28.0802421641979x=3 y=18.7201614427986x=4 y=14.040121082099x=5 y=11.2320968656792x=6 y=9.36008072139932x=7 y=8.02292...
