x^x-x=24,rt1679年,莱布尼茨写信给惠更斯讨论方程:x^x-x=24x^z+z^x=bx^x+z^z=c

(x+y-z)(x-y+z)= z=x X+Y+Z=? c语言：z=x f(x,y,z,w)=x*(x+y)*(x+y+z)*(x+y+z+w) 已知a（y-z)+b(z-x)+c(x-y)=0求证(cy-bz)/y-z=(az-cx)/z-x=(bx-ay)/x- x y z x+y--- = --- = ---- ----y+Z z+x x+y ,求 z 的值 .求 x+y---- 1.设有比例式：x/(y+z)=y/(x+z)=z/(x+y),有比例性质,得x/(y+z)=y/(x+z)=z/(x+ 已知x+y-z/z=x-y+z/y=-x+y+z/x,且xyz不等于0,求分式[(x+y)(x+z)(y+z)]/xyz 若z分之x+y+z=y分之x-y+z=x分之-x+y+z,求xyz分之(x+y)(y+z)(z+x) y+z÷x=Z+X÷y=X+Y÷z,X+Y+Z不等0求X+Y-Z÷X+Y+z值 (x+y-z)/z=(y+z-x)/x=(z+x-y)/y 求(x+y)(y+z)(z+x)/xyz
