• 几道数学题 麻烦高手解下1.已知10^a=A,10^b=B,10^c=C,且a+b+c=0.求证:A^1/b+1/c·B^1/c+1/a·C^1/a+1/b=1/1000 2.求证：a1+(1-a1)a2+(1-a1)(1-a2)a3+……+(1-a1)(1-a2)……(1-am-1)am=1-(1-a1)(1-a2)……(1-am)注：像a1,a2,a3…这样的 ,a旁边那个数字是指a下面角标.3.已知1/x+1/y+1/z=1/(x+y+z).求证：1/x^(2n+1) + 1/y^(2n+1) + 1/z^(2n+1)=1/x^(2n+1)+y^(2n+1)+z^(2n+1)请大家帮帮忙```能解一道题的也十分谢谢```第3题是3.已知1/x+1/y+1/z=1/(x+y+z)。求证：1/x^(2n+1) + 1/y^(2n+1) + 1/z^(2n+1)=1/[x^(2n+1)+y^(2n+1)+z^(2n+1) ]可爱孝柔```你貌似没好好读题哇````请愿意帮忙的好生读下题```谢谢了
• a/x*x-yz=b/y*y-zx=c/z*z-xy求证ax+by+cz=(x+y+z)*(a+b+c)
• a/x^2-yz=b/y^2-zx=c/z^2-xy xyz=0 求证ax+by+cz=(a+b+c)(x+y+z)
• 已知x,y,z,均大于0,求证x²/a+y²/b+z²/c≥ (x+y+z)²/(a+b+c)
• 若a/x^2-yz=b/y^2-zx=c/z^2-xy,求证ax+by+cz=(a+b+c)(x+y+z)
• 1.已知x,y,z∈R,且x+y+z=a 求证x^2+y^2+z^2≥(a^2)/3 2.已知a、b、c>0,a+b+c=1
• 已知a/(x2-yz)=b/(y2-zx)=c/(x2-xy) 求证ax+by+cz=(x+y+z)(a+b+c) 我要过程,那种看不懂的别抄过来
• a/x*x-yz=b/y*y-zx=c/z*z-xy求证ax+by+cz=(x+y+z)*(a+b+c)
• 6.设a,b,c,x,y,z是正数,且a2+b2+c2=1 0,x2+y2+z2=40,ax+by+cz=20,则( a+b+c )/(x+y+z)=
• 若a/x^2-yz=b/y^2-zx=c/z^2-xy,求证ax+by+cz=(a+b+c)(x+y+z)
• 已知x,y,z∈R,a,b,c∈R+,求证(b+c)/ax^2+(c+a)/by^2+(a+b)/cz^2 ≥2(xy+yz+zx)要过程
• ax=by=cz=1,求(1/1+a4)+(1/1+b4)+(1/1+c4)+(1/1+x4)+(1/1+y4)+(1/1+Z4)= (4:4次方）
