If x = 255, y = 256, z = 257, then find the value of x^3+y^3+z^3-3xyz . यदि x = 255, y = 256, z = 257 है, तो x^3+y^3+z^3-3xyz का मान ज्ञात कीजिए ।

x+y+z=1 x-2y+3z=2 5x-3y+z=3

2x-3y+5z=16, 3x+ 2y-4z= -4, x + y - 2z =- 3.

2x+3y+3z=5 x-2y+z=-4 3x-y-2z=3

If x + y + z = 10, x^3+y^3+z^3=75 and xyz = 15, then find the value of x^2+y^2+z^2 -xy-yz-zx यदि x + y + z = 10, x^3+y^3+z^3=75 तथा xyz = 15 है, तो x^2+y^2+z^2 -xy-yz-zx का मान ज्ञात कीजिए।

If x+y = 4, xy = 2, y+z = 5, yz = 3, z+x = 6 and zx = 4, then find the value of x^3+y^3+z^3-3xyz यदि x+y = 4, xy = 2, y+z = 5, yz = 3, z+x = 6 और zx = 4 है, तो x^3+y^3+z^3-3xyz का मान ज्ञात करें

x+2y-2z=5,3x-y+z=8,x+y-z=4

2x + 3y-5z = 7, x + y + z = 6,3x-4y + 2z = 1, then x =

2x + 3y + 3z = 5, x-2y + z = -4,3x-y-2z = 3
