Объяснение:
f(x;y;z)=x²e^(y*z)
fx=2x*e^(y*z)
fxy=2x*e^(y*z)*z
fxyz=2x*e^(y*z)+2x*e^(y*z)*z*y
fxx=2*e^(y*z)
x*fxx=2x*e^(y*z)
fy=x²e^(y*z)*z
fyy=x²e^(y*z)*z²
y²*fyy=x²*y²*z²*e^(y*z)
z²*fzz=x²*y²*z²*e^(y*z)
fxyz-x*fxx+y²*fyy-z²*fzz =
2x*e^(y*z)+2x*e^(y*z)*z*y -2x*e^(y*z)+x²*y²*z²*e^(y*z)-x²*y²*z²*e^(y*z)=
2x*e^(y*z)*z*y
