Evaluate `x^3+y^3+z^3-3xyz` when x=2, y=-1 and z=3.

Find the value of : x^3+y^3+3xyz given that x=-1,y=2 and z=3

Let's write the value of x^3 - y^3 -z^3 - 3xyz if x = y + z

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 ।

If x+y+z=2, xy+yz+zx= 11, then the value of x^3 +y^3 +z^3 - 3xyz is: यदि x+y+z=2, है, xy+yz+zx= 11 है तो x^3 +y^3 +z^3 - 3xyz का मान होगाः

If x+y+z=2, xy+yz+zx=-11, then the value of x^3+y^3+z^3-3xyz is : यदि x+y+z=2, xy+yz+zx=-11 है ,तो x^3+y^3+z^3-3xyz का मान ज्ञात करें |

If u = log (x^(3) + y^(3) + z^(3) - 3xyz) , then (x + y + z)(u_(x) + u_(y) + u_(z)) is equal to

If x = 1, y = - 2 and z = 3. find the value of (i) x^(3) + y^(3) + z^3-3xyz (ii) 3xy^(4) - 15 x^(2) y + 4z

Verify that x ^(3) + y ^(3) + z ^(3) - 3xyz =1/2 (x + y + z) [(x-y)^(2) + (y-z) ^(2) + (z-x) ^(2) ]

Verify that x ^(3) + y ^(3) + z ^(3) - 3xyz =1/2 (x + y + z) [(x-y)^(2) + (y-z) ^(2) + (z-x) ^(2) ]

Verify that x ^(3) + y ^(3) + z ^(3) - 3xyz =1/2 (x + y + z) [(x-y)^(2) + (y-z) ^(2) + (z-x) ^(2) ]
