Question

if X + Y + Z is equal to zero, then what is the value of x cube + y cube + Z cube

Answer 1

0 because the value of x y and z is 0 and by multiplying alphabets we get the number it self or 0

Answer 2

x ^3 + y^3 + z^3 = (x + y + z ) (x^2 +y^2 + z^2 - xy - yz - zx)

x + y + z = 0 ( data )

then x cubed plus y cubed plus z cubed = 0( x^2 + y^2 + z^2 -xy - yz - zx)

when a number is multiplied by 0, the answer is 0. 

so x^3 + y^3 + z^3 = 0

hope i helped ya!!! 
if i did, plzzzzzzzz mark me brainliest!!! :)
