OK
= (x^2y^2+y^2z^2+x^2z^2) + ( x^4-y^2z^2) + ( y^4-x^2z^2)+(z^4-x^2y^2)
= x^2y^2+y^2z^2+x^2z^2 + x^4 - y^2z^2 + y^4-x^2z^2+z^4-x^2y^2
=( x^2y^2-x^2y^2)+(y^2z^2-y^2z^2)+ (x^2z^2-x^2z^2) + (x^4+y^4+z^4)
= (x^2+y^2+z^2)^2
= 10^2 (vì x^2+y^2+z^2=10)
=100
mk nhầm. k sửa lại r( x^2y^2-x^2y^2)+(y^2z^2-y^2z^2)+ (x^2z^2-x^2z^2) + (x^4+y^4+z^4)
