Answer 2

THE ALZEBRIC FORMULA FOR (X+Y+Z)³

⇒ (X+Y+Z)³ = X³+ Y³+ Z³+ 3(X+Y)(Y+Z)(Z+X)

suppose we are given x=1 y=2 z=3

substituting the values,

(1+2+3)³= 1³+ 2³+ 3³ + 3(1+2)(2+3)(3+1)

solving the values,

            = 1+ 8+ 27+ 3(3)(5)(4)

multiplying and adding,

            = 36+ 180

            = 216.

HENCE IN THIS WAY, THE FORMULA CAN BE USED.
