The inertial mass will be the same anywhere because it is only weight that varies with gravitational energy.

Am sorry that this is post in the wrong position but this is the solution x^2+y^2+z^2=(x+y+z)^2-2(xy+yz+zx)=35 substitute x+y+z=1 we have (1)^2-2(xy+yz+zx)=35 therefore (xy+yz+zx)=-17 also x^3+y^3+z^3=(x+y+z)^3-3(x+y+z)(xy+yz+zx)+3(xyz)=97 therefore substitute we have (1)^3-3(1)(-17)+3(xyz)=97...

You are correctbut why don't you show your working?

That's very good

Can any solve this x+y+z=1 x^2+y^2+z^2=35 x^3+y^3+z^3=97

How can you solve this question x+y+z=1 x^2+y^2+z^2=35 x^3+y^3+z^3=97
